Me and my other friends who have the G1 also noticed this...ok i like google talk but all of my friends are on AIM, i had the sidekick lx before i upgraded, so of course i wanna keep talkin to my sidekick friends, but its hard to do that when on the G1 it signs u off without u knowing until u look at your buddy list and it shows everyone is offline when they aren't.
Is anyone else noticing this? it really annoying, hopefully the next update will fix this
