...(gingerbread) without a PC? I have a t-mobile Motorola defy and I need to update it from 2.2 to 2.3 WITHOUT a computer (I don't have one or easy access to one). My phone is already rooted but I have no experience with installing Rom's or anything like that..

I need it because a lot of the apps I want to use require android 2.3 or higher and I don't have the money to buy a new phone. I've been looking at discussion boards and forums and videos for days but every method of updating requires a computer. Please help!
