Is there any program that allows mail syncing/downloading in the background like Sprint BC? I love Snapper Mail, but find the display turning on each time it is downloading and the inability to use any other programs until it is complete annoying and cumbersome. I've found Sprint BC to unreliable and very limited (as everything with Sprint). I also have a GSM T600 on the way, so suggestions on a program that does this with GPRS would also be helpful.
