For some reason, I can't get the 770 to sign into my gtalk account. It worked once, I made some calls and it was fine, but now it won't sign in.

The indicator flashes between red and whatever other mode it is attempting to use (i.e, online or away or invisible), but there is little/no traffic sent over the wi-fi it is connected to. After about 3 minutes the 770 gives up and says "Unable to connect to one or more accounts".

I've tried removing the account and re-adding it, restarting the device, trying a different account and using GPRS as the internet connection rather than wi-fi, all without success...

Anyone got any bright ideas?

Edit:

I'm aware that 2006 is still in Beta. I'm just asking if anyone knows a fix for this issue, or even if anyone else has the issue?
