Several reports have pointed to problems with iTunes crashing after installing the v2.2.1 firmware update on the iPhone. After running the update, a number of users have claimed that iPhones will no longer sync with iTunes. In some cases iPhones may sync for a short period of time, but eventually crash when attempting to delete songs.
Apple has not yet verified if the update is the cause of the crashes, or when some form of solution might be available.
I think LG Prada 2 is much better than iphone.
