I did jailbreak my iPhone some time ago, but I played (messed) too much with it, so I decided to erase it and reinstall. I did jailbreak many times before - iPod 1st and 2nd generation, and iPhone 3G.
But now, when I reinstalled quickpwn does not recognize my iPhone. When I tried pwnage tool it said that firmware that I have chosen is wrong. And when I tried to check with iFantastic it did not recognized my iPhone as well. iTunes works normally.
pwnage tool 2.0
os x 10.5.7
Does anyone has the same problem? Or better, does anyone have some advice?
-EDIT- I have found some computer with windows and I did jailbreak there without any problems. I remember that I did some big os update recently on my mac. Most probably there is some new bug to avoid jailbreak.
