Pwnage 3.1.2 unlock SMS - text messages not working

[robdxb]

I'm on a 2G iPhone and couldn't receive or send sms text messages after upgrading to 3.1 and then 3.1.2.
Initially after the upgrade texting worked fine, but after restoring the iPhone backup in iTunes, sending a text in the Message application would quit to the desktop.
Also, if I deleted message "conversations" (either using Edit or swiping and deleting a text message) and then quit the Message application, on re-opening Messages the sms threads would be back. They simply wouldn't delete!
A solution that is working (for me anyway) was:
1/. Use Cydia to install OpenSSH on the iPhone.
2/. Use CyberDuck on the Mac and go to /User/Library/SMS and copy sms.db to the Mac Desktop as a backup.
3/. Take a deep breath then delete sms.db on the iPhone (Option+click then select delete)
3/. Restart iPhone. All SMS conversations are gone but texting works.
However, just for the heck of it I then copied the old sms.db back from the Mac desktop to /User/Library/SMS and rebooted the iPhone - the result was that all old conversations were back AND texting worked again!

THANKS!

I had the same problem but with MMS, followed these steps exactly and now MMS is working!

NOTE: make sure you reboot after the last step!

Refering to the soultion given in this topic, Backingup/Restoring sms.db Help Please!!! Urgent, when you restore the backed up sms.db, you have to change the "group ownership" of the file to "mobile" this can be done via iFile or WinSCP
