Same problem here except mine will do it randomly during any sort of send/receive, manual or automatic it doesn't matter, kicks me to the home screen. I have nothing installed on my phone either. Base Sprint phone, I've even hard reset it trying to fix it. I'm chopping at the bit for a new ROM to come out in hopes that it will fix it.

I have another issue with it endlessly vibrating when a new email comes in until I open the message and another where the dropdown balloon that shows me a quick preview of a new email or missed call never drops down. I have to click the icon at the top and then it will drop. Real PITA
