just a quick thing, a while ago i had a problem with my jailbroken ipod, where that after a while i could no longer install any more apps, everytime i would attempt, the installer would download the package, then just when it finished, it would crash the installer and be unable to install the app, I also found that i could not SSH the apps into the ipod either. I did a restore, the whole downgrade jailbreak, upgrade thing, and after it was fine. for a while. now its happening again. I was just wondering if there is any way to sort this problem once and for all? One last thing before i go, a friend wants me to jailbreak his 1.1.2 ipod, he has a pc, i have a mac, will this effect anything at all?
