Ok ... Since I just jailbreak my ipad2 I was eager to do the same to my aging iphone3gs (waiting on the ip5). I think I leaped before I looked so ... Updated my phone os to 4.3.3 and tried the cydia dl from jailbreakme.com..... And everytime I try to dl it (cydia) icon would appear as with the loading bar and before it finishes it disappears.. Messed up ain't it? Short of a restore, any suggestions?
