Did the upgrade yesterday on my 3g and everything seemed fine. Battery went red last light so charged it up overnight battery still red this morning.
Currently got it plugged into my computer at work. Showing the charging symbol but as soon as I take it off charge it's still red and has not moved. Computer USB is showing iPhone attached too.

Anybody else??

You using the same USB cable or a different one? Try a different one if not.

Then try a full restart holding home key and lock key for about 15 seconds.

Could be the battery is buggered though.

Using a different (offical) cable.

Just tried a full reset and it seems to have worked. Now showing full battery as expected. Cheers Drac must just have been the battery symbol not updating. Grrrr those gremlins in the machine….

Yeah full reset often works when they play up.
