How To Root Android 2.3 Gingerbread Using GingerBreak. Rooting Android devices on 2.3 Gingerbread Stock ROMs may just have been simplified to an almost one click method with GingerBreak and it’s close to a universal solution for most phones, but we can’t confirm all of those.
We tested it out on our HTC T-Mobile G2 running the leaked 2.3.3 Gingerbread from HTC, and it worked liked a charm and there have been people who report it to be working for the Sony Ericsson Xperia Arc as well. Of course there will be devices that this solution may not work on for now, but hopefully future updates may help cater it a larger variety of Android devices.
