Want to go to Apex2.0 from 1.4
So I rooted my phone a month (or so) ago and went with the Apex1.4.1 ROM. I like it, but lately it's been giving me a little grief (rebooting on its own, giving me a process fail sometimes)....so, I'd like to move to 2.0. Looking into it I need to have Gingerbread etc. to put 2.0 on. First of all, WTF is Gingerbread? Second, is putting it on like flashing the ROM all over again, and once I flash that on then I put 2.0 on? Could someone please give me a helping hand? Thanks in advance!
