I have a LG Optimus P500 from T-mobile which is unlocked to all GSM sims. It runs Fryo 2.2 and I would like to upgrade to Gingerbread 2.3.x. Is it possible to do that? Would that lock or brick the phone? Is there any way that I could install gingerbread 2.3.x since I don't also see T-mobile official gingerbread release anywhere for P500. Is KDZ an option or should I stick with Fryo?
