Ok guys, thanks for your answers, I have another question, not so silly this time.
there are 3 roms that caught my eye here
(for the optimus v) I have try them all, and I don't see any difference between them.
1) mrg666: CM7.2-RC0-IHO-MiRaGe. latest version (Dec 1, 2011)
2) JerryScript: BACKside (not pure). latest version (Nov 22, 2011)
3) BobZhome: CM7.2.0 RC0-BobZ. latest version (November 19, 2011)
I have seen the change logs for (2) and (3), the one for (1) I just couldn't find it anywhere.
would you be so kind of telling me the differences and also recommending the most stable one (that would be for my wife, I don't want her phone rebooting or anything like that because she is not a ROM junkie like myself
Thank you very much.
