Here my problem, I first jailbroken my iPhone 4 on 4.2.1 when the untethered jb came out with gp. Everything was all ok. Then a month or so down the line something messed up so I done a clean restore then jb, again with the latest gp.
Not sure if it's a coinsedence and i didn't noticebut recently my app store won't load. It hangs for about 10 seconds then goes back to springboard.
Anybody know any fixes? Will I have to re jb? If that's the case then i'll wait for 4.3 gp jb untethered to arrive but i've read today an untethered jb won't arrive till 4.3.1.
