Rooting Android - General Observations and OG Droid + LG Ally
After a couple years having had no experience with an Android phone of any variety, a generous Twitter follower I had met donated two older Android phones, an original Motorola Droid (running Froyo 2.2.2) and an LG Ally (also running 2.2.2), so I could learn the Android UI and work on porting a couple of my iOS apps.
One unfortunate reality of the Android ecosystem is that phones are often abandoned by their manufacturers after only a year (or less time), and even if not, they are not kept up to date past one or two minor Android OS releases. For instance, both the Ally and Droid are more than capable of running Android 2.3 Gingerbread (and I'm now running 2.3.7 on the Droid, faster than 2.2.x ever ran), but Motorola has ended support for the device.
