If, like me, you have an old iPod lying around and want to make use of it, read on:
I bought an iPod Touch (2G) (Model #MC086KH/A) in Korea a few years ago. After finally getting an Android phone, I didn't have much use for it anymore, and I nearly forgot about it in my desk. I recently rediscovered it, to find that it can only be updated to iOS 4.2.1. At less than iOS 4.3, there aren't many decent apps that can be used with it.
There is a custom firmware called whited00r, but it only works with the MB-series models of the 2G iPod Touch.
At least wanting to jailbreak it, I discovered that most modern jailbreak methods no longer support the older iOS versions. However, I had success using this method on Lifehacker.
So now, through a combination of Veency (on the iPod) and Android VNC Viewer on the android phone, I have the iPod permanently attached to a set of speakers above my refrigerator, and can control it from anywhere in the house (including MP3 playback and, most commonly, streaming radio). There's an excellent and simple tutorial for accomplishing this here.
Nice way to bring an old piece of tech back to life. Hope this helps others as well!
