I have an ATT Captivate which I managed to update from original Android 2.1 to 2.2 firmware, version I897UCJI6.
This was before ATT release their official 2.2 update.
I also managed to unlock the phone.
I have to admit I am totally ignorant of this stuff, and I was lucky enough not to brick my phone during those updates.
I am very unhappy with the battery life of my phone, and I read that the Gingerbread dramatically improves this aspect.
So, shall I upgrade to Gingerbread?
If yes, I am confused with the many sites which offer advice with how to do this, some contradicting with others. (One indicated to reverse back to 2.1 before upgrading to 2.3, other didn't say that, etc etc)
Should this upgrade be successfull, what happens to the lock/unlock status?
Do I need to unlock again?
Which is a trusted site?
Any advice?
Thank you for any help
