so i jailbreaked 3.0 for my iphone 3g , got it running, then i had some trouble to update cydia before installing ultrasn0w, so i had to try a couple of times but got it unlocked. a coulple days after i wanted to install cycorder, but i couldnt at the first try, but i got it running. now when i open cydia i get a red label saying that cydia doesnt know which version it is and so on. after reading about the problem, they recommend to rejailbreak the iphone and uncheck icy. but my question is, will i loose my itunes apps i've downloaded, the cydia ones, will i loose ultrasn0w and lock my iphone up again, and loose my contact info? have anyone had this problem before? please help, cydia is working really bad
