Ive just upgraded my iphone OS to 4.3.1 & can no longer pick up any signal (locations in London where I have had no problem in the past & other phones are fine), I seen to permanently have the No Service message in the top left.
So far I have tried:
switching it on & off
resetting using the sleep & home button
resetting the network settings
restoring from a backup
taking the simcard out & putting it back in again
Nothing has worked so far. As i understand there is no rollback procedure with Apple OS, is there anything else I can try?
Not sure if it makes any difference but I have a Dutch T-mobile simcard but theres never been a problem using it back in London or upgrading in London. Any help appreciated!

In case any one else is having the same problem I just did a full factory reset (& then loaded a back up profile) & it solved the issue.
