i keep getting a notification "google talk authentication failed". and it seems that i can't download from market til i fix it. i've already tried adding another gmail account. although it does fix the problem it's only until i reboot the phone, then i have to remove account and then add it again. i've also tried doing a factory reset, wiped dal vik cache, and c&p'ed another google tak into system/app folder. anyone know a permanent fix for this?
