iPhone loses SMSs after software update

Question

I recently updated my iPhone 4 to iOS 4.3.1. Everything seemed to go fine. However, after I sent my next text message the phone quickly showed the restart screen and then all my old messages were deleted. Thinking it was a fluke I restored to before the update. Everything (except the messages I had sent between the update and restore) showed up again. However, again, as soon as I sent another text, my phone restarted and all the old messages were removed. I'd like to keep my old SMSs on my phone and still be able to send/receive new ones.

Any ideas?

The best answer I can give you is to go the Apple Store Genius Bar or your local Apple Authorized reseller. That certainly seems like a particularly bad bug.

I can only hope that it has been fixed in the year since you posted this question.

Open up "Settings" then tap on "General" and scroll down to the last option "Reset". Tap the third option "Reset Network Settings". This will take a few seconds and then your phone will restart.

BE ADVISED Doing this will deleted your saved wireless network passwords and wireless network history so you will have to reenter these passwords to reconnect to wireless networks. This option does not delete any of your personal data off your phone.

f you have back up your text messages, you can restore from the backup.

To restore information from a backup, use one of the following methods after connecting your phone to the computer with which you normally sync: 1. Right-click (or Control-click) the device and choose Restore from Backup 2. If you have a new phone, you can connect to iTunes and it will prompt to restore from your backup Solution from Apple.com: http://support.apple.com/kb/ht1766

If you have no backup for your SMS messages, iPhone SMS recovery software is your last shot! Just a few clicks you can get all your data back.
