I've had my 650 since Dec (and a 600 for 14 mths prior) and have a new issue that just cropped up today that I've never seen addressed here before (and I did search):

When I push the email button on the phone to go to Sprint Business Connection, the screen goes blank and the phone locks up. The green led continues to flash periodically, but I have to hit the reset button on the back to get control back. From the phone screen, I can see there's 1 email unread and when I click on that, it depresses as if it's going to go into my email and then takes me right back to the phone screen.

No new software has been added in 2+ months nor am I running anything too fancy on here.

Any help?
