This problem has never happened to me before and I've also never heard of it and can't find any information about it anywhere. I have an unlocked jailbroken iphone that's never given me any serious problems for about a year. When I click the text icon, the top of the screen reads: Text messages (-1) Where all my listed text messages used to be it is now blank. When I try to send a text after typing in the contact name or number it immediately says: Error sending message I tried restarting the iphone. I can send and receive phone calls perfectly. Anyone ever had this problem or have any advice?
