Right on cue with recent reports from “insiders” and “people familiar with the matter”, Apple has gone ahead and sent out invitations to media outlets announcing a March 7th media event where the company will unveil the iPad 3.

Of course Apple had to announce it in the middle of one of the largest annual mobile tech trade shows, Mobile World Congres, which is going on right this very moment in Barcelona. Most major TV news outlets in the US are likely to be entirely unaware of the event, but I’m willing to bet there will be several mentions of Apple’s event announcement (read that again: you’ll see news covering an event announcement rather than a huge event in itself, just because the announcement is from Apple).

To honor the folks that, no doubt, spent a good deal of time and trouble preparing and reporting on all of happenings at MWC (from those who designed devices, to PR people, marketers, journalists, etc.), I’m going to open this post first with a list of all the exciting stuff we’ve seen so far from MWC. If you want coverage about Apple’s event announcement, it’s tucked neatly away at the end of this article.

Exciting Announcements from MWC!

• Qualcomm Snapdragon S4 – Quad Core Krait Demo
• ASUS Padfone 2012. Hands-on with Phone, Dock and James Bond Pen!
• Mirasol Transflective Displays. Faster, Brighter, Touch-Enabled. (Product Update Video)
• Samsung Galaxy Note 10.1 Brings Digital Inking and Photoshop to the Big Screen!
• Previously Leaked Asus Transformer 300 Revealed, Asus Taking the Transformer Prime Mainstream?

And now on to your regularly scheduled content:

The high resolution iPad 3 retina display (2048×1536), that made the rounds a little more than a week ago, has all but been confirmed at this point; any iPad original or iPad 2 owner will be able to tell you that the text and icons as seen on the iPad shown in the invite is far sharper than that of any iPad released thus far.

Apple’s typical clever symbolism is also present in the invite photo; you can see the date on the calendar icon as March 7th, the location with the map icon is (as always) Apple’s famous 1 Infinite Loop, Cupertino address (though the event is actually going to be at the Yerba Buena Center for the Arts), and the Keynote icon is obviously a reference to the presentation that will be given. The time for the event is 10 AM PST (1PM EST) as usual.

We don’t know much more about the iPad 3 than the high-resolution display and that it will have a similar case to the iPad 2 (possibly slightly thicker). Some accounts say it will be running a new quad-core A6 CPU, while others contest that it will be an updated dual-core ‘A5X’. I speculated back in July of 2011 that the iPad 3 would be the first iPad to include 4G LTE and I’m still sticking with it. I also recently prepared a list of what Apple would need to include in the iPad 3 for me to justify adding a ‘third device’ to my life — I doubt we’ll see much of what’s on the list, but you never know!

If you’re looking for rampant speculation (always popular with Apple topics), let’s take the invitation text, “We have something you really have to see. And touch,” out on a ridiculous limb: Something we have to see? Well, we wouldn’t be able to tell if it is a glasses-free 3D display from a 2D photo, so perhaps that is in store in addition to the retina display? And something we have to touch? Maybe Apple has come up with some revolutionary tactile display technology that allows you to ‘feel’ on screen elements?

In all likelihood, this will be an incremental increase, without anything too wild, which will further solidify the leading tablet on the market.

For the last few weeks photos of purported prototype iPad 3 displays were floating around the web. Now, MacRumors actually got their hands on one and actually examined it under a microscope to confirm the resolution.

Their findings show pretty conclusively that the screen has twice the pixel density as the screen on the iPad and iPad 2:

The original iPad and iPad 2 both have a 9.7″ 1024×768 IPS display with a total of 786,432 pixels at 130.61 PPI. At twice the density, the screen that MacRumors got their hands on would be 2048×1536 (presumably also IPS), which amounts to a whopping 3,145,728 pixels at 261.22 PPI. Compare this to 1080p HDTV resolution which is 1920×1080 and 2,073,600 pixels total. Although this screen has an impressive resolution, it’s actually not all that pixel dense. The iPhone 4 and iPhone 4S retina screen is 960×640 at 329.65 PPI.

Doubling the size of the screen on the iPad will do a lot for the aesthetics of the UI. Going from an iPhone 4S screen to the current-generation iPad screen really reveals how much sharper the iPhone’s screen is. I’ve heard a number of people say that the iPad would make a far better e-Reader if it had a more pixel-dense screen.

Rumors about a retina display on the iPad have been around ever since the original iPad launched. But is this really the iPad 3’s screen? I trust that the folks at MacRumors have been able to correctly identify this as an iPad screen, but are we sure it’s for the iPad 3? We’ve seen lots of evidence about of Apple products attributed to prototype parts that may or may not ever make it into the final product. Recall all the rumors surrounding the ‘iPhone 5’ (which turned out to be the iPhone 4S) launch. It’s even possible that this particular screen is part of ongoing work on the iPad 4.

For now, all we know for certain is that this is an iPad screen, and it’s definitely 2048×1536. Will it make it onto the iPad 3? Apple is expected to announce the iPad 3 at the beginning of next month… only time will tell.

We’re not into Apple rumors here at Carrypad, but what we are into is informed speculation. Join us for some healthy analysis about when and how Apple will make the move to 4G.

Based on Apple’s Q3 sales figures that were just released today, it’s clear that Apple is doing extremely well, even without a single 4G product in its stables.

This is interesting because 4G is one of the only areas where the iPhone and iPad are behind, rather than being ahead of, or at least on-par with, the competition.

For all intents and purposes, let’s consider HSPA+, LTE, and WiMax all ‘4G’ networks, as they’re all capable of delivering speeds that are well beyond earlier 3G connections.

The Competition

Verizon has now launched three 4G (LTE) smartphones, and is poised to launch at least one more (the Droid Bionic) toward the end of this summer. They also have the 4G enabled Samsung Galaxy Tab 10.1, as well as the Motorola Xoom which is supposedly going to be the recipient of a 4G hardware upgrade at some point. Additionally, they’ve got a 4G MiFi wireless hotspot and 4G USB modem. [See this article for a roadmap of Verizon’s upcoming 4G smartphones and devices].

AT&T has three 4G (HSPA+) smartphones currently launched, along with a 4G USB modem.

Sprint has fourteen 4G (WiMax) devices available. They’ve got smartphones, tablets, laptops, mobile hotspots, and USB modems. Though WiMax technically has the capability to support 4G speeds, the research I’ve done has indicated that Sprint’s WiMax is sorely lacking in speed, but I’m still putting it on the list because the tech that supports high speeds is already in place in these devices.

T-Mobile has claims to have twelve 4G (HSPA+) devices. They have 7 smartphones, 2 tablets, 2 USB modems, and a mobile hotspot.

What Form Will Apple 4G Come In?

Because Apple currently makes iPhone 4 and iPad 2 models for both AT&T Verizon, it holds that we’ll continue to see those two carriers supported for upcoming tablets and smartphones from Apple.

For the short term, AT&T is relying on HSPA+ to provide 4G speeds to its line of HSPA+ equipped phones; the company often sticks ‘4G’ to the end of the phone’s name to indicate the additional speed (even if some don’t consider HSPA+ to be ‘4G’ from a technical standpoint). In the long term, AT&T is planning on moving in the LTE direction starting this year.

Verizon jumped directly to 4G in the form of LTE, and they seem to have the best 4G speeds so far.

With the two currently supported carriers either already using LTE or eventually moving to LTE, my best guess is that Apple’s first 4G devices will be LTE compatible rather than WiMax or HSPA+, though as you’ll see below, we might end up with a combination of these.

Why Doesn’t Apple Already Have 4G When Others Do?

The technology for Apple to launch their devices with 4G exists, but I believe two factors have held Apple back so far.

Coverage
It doesn’t make sense for Apple to fork over additional money for 4G chipsets if the coverage isn’t already there. If Apple launched a 4G (LTE) iPhone 4 when it announced the Verizon iPhone back in January, it wouldn’t have had a big demographic to sell to because a relatively small number of areas where covered at the time. Passing on the price of 4G hardware to all customers, when only a small portion are actually in 4G covered areas, wouldn’t be good for Apple’s bottom line. It made more sense for them to keep the price attractive until 4G LTE sees widespread coverage.

Battery Life
Battery life on existing 4G LTE devices is still much shorter than 3G devices. I’ve been using the HTC Thunderbolt and LG Revolution and both 4G equipped devices from Verizon have had a hard time providing me with usable all day battery life. Battery life is a major concern for Apple, and I know that they aren’t willing to release a device without all day battery life under typical use.

With every release of the iPhone, Apple has increased performance and battery life. Releasing a 4G iPhone before the technology can come down to a reasonable power consumption level wouldn’t be acceptable for Apple.

When Will it Happen?

The real question is not if, but when. Apple has been wildly successful with the iPhone and iPad, even though the market is already brimming with 4G devices, but that won’t last forever.

Ideally, Apple would launch a 4G iPhone and 4G iPad when the two above factors, coverage and battery life, align. Unfortunately, Apple is now being pressured by all of the other 4G devices on the market.

Verizon’s 4G LTE forecast indicates that they hope to have their entire 3G network area covered with 4G LTE coverage by 2013.

AT&T is launching its first 4G LTE coverage areas this year, but the rollout is going to take time, and they’ll most likely be lagging behind Verizon in 4G LTE coverage in 2013.

The iPhone 5 is expected to be released in 2011, and the iPad 3 likely won’t come until 2012. In terms of coverage, the time is not ideal for Apple to launch a 4G iPhone 5 or 4G iPad 3.

I think that Apple would rather wait for two more product generations before releasing 4G devices (so that power consumption can come down and coverage can increase), which would mean 4G LTE compatibility with the iPhone 6 and iPad 4, but I doubt that they can wait that long.

An interim HSPA+ iPhone 5 might be more practical for Apple, but it would leave Verizon users in the rain as Verizon has no HSPA+ infrastructure.

A compromise could be for Apple to release a 4G (LTE) iPhone 5 on Verizon and a 4G (HSPA+) iPhone 5 on AT&T. I would expect that release in 2011, but the iPad 3 will likely not be released until 2012. At that time, LTE network coverage should be more favorable for AT&T, and Apple may launch a 4G (LTE) iPad 3 for both networks, then eventually bring LTE to their AT&T iPhone offering with the release of the iPhone 6 in 2012. This is a bit confusing in text, so I’ve put together a timeline (apologies if the large timeline runs off the screen on mobile browsers!):

Some might see the release of a separate HSPA+ and LTE iPhone 5 and iPad 3 as unlikely, but it should be considered as Apple currently has two separate versions of the iPhone 4 and iPad 2, one for AT&T’s HSPA 3G network, and one for Verizon’s EVDO 3G network.

Though the LTE coverage is not quite optimal for the upcoming iPhone 5, Apple can’t ignore 4G as it’s starting to be expected from the latest phones (and every major US carrier is pushing the buzz word like their life depends on it). I can’t see Apple releasing the iPhone 5 without 4G, whether that be HSPA+ or LTE.

I would certainly reconsider purchasing the next iPhone if they release it without some form of 4G. How about our readers does 4G availability influence your smartphone purchasing decisions?
