On friday evening, I got the message from my iPhone 5 on iOS 6.1.2 Ever since that message, I do NOT receive SMS messages but I can send them out just fine. (iMessage works normally as well) I went ahead and deleted threads and even used a cleaner app to clean 3 GB worth of attachments. Nothing has changed. I know this is specific to my phone because I am receive text messages when I transfer my SIM card to other iPhones. My phone is jailbroken with biteSMS and LockInfo. Are there any other steps I can take so that my iPhone receives and displays SMS messages so I don't have to go and restore it?
