I'm having the following issues:
- 'Market' not functioning ('A network error has occurred. Retry, or cancel...')
- Gmail not functioning ('No connection')
- Red triangle in top-left of screen = 'Sign-in-error (email address)'
I think these issues are related to the problems I am having with sync-ing Contacts / Calender / Memo with the PC. The process stalls at 25% completion.
The phone also seems to be slower to respond lately.
