Good news, last night using Zite I read that Apple will be coming out with a fix soon for the ID touch which should help. The article read that they are working on a fix for the problem. I read several articles that a fix is coming soon or may be incorporated into the next iOS update.
Oooh good. Does anyone else get it sometimes where it just refuses to even scan the finger? Also does anyone ever get like stuck in an app for a while until the hone reboots? (It just sits there in the app and you can't exit it with the home button or lock it. The most you can do it to hard reset it with both buttons, the App works fine).
