Question about Sony Ericsson K800i Cellular Phone
Sounds like a silly question but did you update the phone via the SE suite or via a flash updater? there may be problems if you left your sim in, if you flashed the phone. If you updated via the SE suite then take a look at the troubleshooting guide and moan to SE. As long as you haven't voided the warrenty on your phone there should be no problem with SE or your service provider repairing your phone for free. :)
Hope this helps. One last thing to try is to out another sim in the phone and see if it works. With any other provider except O2 you will need to use a sim the same as yours.
