So, I've got the mail app set up with my personal IMAP account, automatically checking every 15 min. I then turn off the wifi and a little while later put the touch into standby. A few days go by and I turn on my touch to find a lot of new messages in my inbox. The deal is that I wasn't in a wifi spot at the time. Best I can figure out, the damn thing wakes up every 15 min, enables wifi if available and checks my mail and goes back into standby. I thought, no way. Then it happened a 2nd time today in the airport. I was in Continental's president's club. They've got wifi that I had previously enabled on my touch a few weeks back. I get on the plane, having never even pulled my touch out of my computer bag, and there ya go... a bunch of new emails sitting on it from what could only have been access there at the club when I had no clue. Cool. But sort of tripped me out a bit.
