Tnkgrl has been on a modding-spree with her new Acer Aspire One [Portal page]. I noted in my review of the Aspire One that some of the important connectivity options were lacking, such as Bluetooth and 3G. Luckily smart people like tnkgrl are here to show us how we can fix some of those important but neglected components.
Moving on to part three of her Aspire One modding-spree, she shows us how to put HSDPA into the Aspire One for 3G connectivity. Amateurs be warned: this is not a simple RAM upgrade, but if you still feel up to the task, tnkgrl has provided a helpful list of steps, images, and a video of making it all happen.
