Okay so I use a first gen iPhone unlocked on T-Mobile. It is running the 2.1 software mainly because it is smooth enough to where I like it and I hate updating because of the whole unlocking business. Anyways, when I plug in my iPhone, it pops up in itunes and says it is syncing but nothing is being synced. Then I try to drag some music into my iPhone and I get the bbod. I then have to unplug the phone and restart the process. It is very annoying and time consuming. What do I need to do? If I do need to update it, is pwnagetool able to update to 2.2.1?
