I just had a friend put mobile installation onto my first generation iphone. he put it in the right place, set the octal/permissions correctly and made a back up (hes knows what hes doing). Now im home at my computer downloading the "stuff" double clicking them for them to be open on itunes and when i try to sync them all i get an error message. i looked up the error and it has to do with my USB ports. and i followed the instructions and suddnely it works and its on my phone. except now i cant open it. i tried to re sync it and now it wont go back on and im back to were i started :[ how do i fix this?
