I used rc9 and it works but when I update my apps from itunes [move back to 4.3.1] all of them could not work and said said some unknown Error. What is going on? Why none of them works? Advise.. what can I do? I use 0.96 of RedSnow Rc9.... [RC12 did not work even in compatibility mode for XP... it showed the pineapple and then says installing bundles, etc.. and then a while later it went blank. I hook it up to iTunes 10.2.1 or something [newest version] and then itunes ask to restore my previous... yes... and then about after 40+ mins.. showed as though it was installed or moving my old apps back... it says of some error. My iPhone 3GS is the newer model so called... could that be the reason? Errror was 0XE8008001. What can I do?.. Got it fixed.
