...the phone? i might need to upgrade to iTunes 10 in order to even be able to use iTunes on my computer now because i made the mistake of downloading and installing iTunes 10 with the assumption it would sync the phone to iTunes and it would work but it did not but i did not update the phone and now any other version of iTunes will not work. if i upgrade everything on iTunes 10 there is still no guarantee it will work but i have no choice now if i want to sync the phone. can i downgrade the phone once it is upgraded in 10 so i can jail break the phone maybe at a later date? if i cannot i might just sell the phone... thanks if this can be answered...
