That's weird- I've logged in to Buzzerbeater successfully with both an iPod Touch 2G and an iPad, and had no problem with timing out. I would make sure your internet connection is secure, and then maybe see if a friend's account works (to find out if it is your BuzzerBeater account or your iPad that is the source of the problem). Troubleshoot with different WiFi areas and try to find out what the problem actually is, and maybe one of the BBs or GMs can help you.
