I recently jailbroke my iPhone 3gs running on 4.0 through jailbreakme.com. All went well, got Cydia and everything, however yesterday I realized that I can't send or receive MMS messages! In fact, when I go on messages, the camera icon has completely disappeared! I rang my carrier (vodafone) and they confirmed that all the settings were correct. They suggested that I should restore my iPhone and that MMS should work again.. However since I have jailbroken my iPhone I have installed many different apps and stuff and I can't really be bothered to re-do everything after restoring.. Is there a way I could fix this?
