Well, I started off last week on Apex 2.0 on .591. Upgraded to P3Droid's .596 "official" leak, rooted/deodexed. Then, when Liberty v.06 came out, I jumped to that. I've noticed that, beyond a doubt, my battery life has decreased on each sequential jump. .596 "official" was slightly worse than Apex 2.0, and Liberty v.06 seems a great deal worse than that. So, I wanna go back to Apex on .591 until the dust settles and some more ROMs come out. Honestly didn't notice a whole lot of change between .591 and .596 anyways, in terms of performance (battery aside). Do I have to SBF back to Froyo and then dick around with upgrading again (shoot me please), or can I simply flash back to .591 from Liberty v.06? Of course, data wipe and all that goes without saying if the answer is yes.
