Can't recieve SMS since 5.1.1 update

[Bantamboy]

Hi, as the title says, since the update (OK, since maybe an hour after the update!) I've not been able to recieve SMS's, they send OK, but I don't get replies. Have tried restarting, have checked the SMS service settings and they appear to be OK. Any ideas?

I suggest that you try to repair the phone software using PC Companion..

Before repairing your device you may want to backup your information first. Check out this topic for more information on how to.
