Unbelievable - the messaging process froze when I tried to read a text using Social Hub. A force close didn't seem to make any difference ... clicked back to the home screen, powered off, waited a minute and restarted. Everything started up fine. Went back to Social Hub only to find that ALL my text threads are gone. E-mails are fine, but all my texts are gone. I know there is no way to undelete text messages, but technically I didn't delete them. They must be stored somewhere. Is they anyway to retrieve them or has the system "deleted" them? Only had the phone just over a month *sobs* - I got rid of my iPhone (which successfully kept every message ever despite several crashes) !!
