I have had my 8100 for a few months now, I upgraded from the 7100. But I seem to be having 3 issues that I cannot locate anyone having trouble with:

1. I have to keep removing the battery because I am unable to receive calls or sms. The signal looks fine. This doesn't happen all the time but can't find a similar reason why it does.
2. When I close out of Password Keeper it keeps me in Multi-Tap mode when I was in Sure-Type before. I have to Enable it again.
3. If I receive a message and my phone is in my holster when I unlock the phone it goes straight into the message for me to read. But the message shows on my Today Theme as Unread. I have to go back into and mark as Unopened then Opened and it is fine.

Has anyone been having these issues or know how to correct?
