Okay one question before I install this new update. Is there any reason to keep all my other ROM backups? Right now I am running SSX 1.0, but I have backups of rubix, apex, stock, and stock with themes...so I could switch ROMs at my convenience. My question is, after I install my stock 2.3.15 backup and accept the new OTA update is there any reason to keep all those backups? If I take the OTA and then try to flash back to one of the ROM backups, wont I be screwed? Just trying to clear some space on my SD card, any and all comments are welcome. P.S. z4root does work on the new update. I just updated the wife's stock phone and z4root rooted it rather quickly. One more question...? What ROMs/Themes work with the new 2.2.1?
