I have a first generation Ipod Touch with software 2.1. Every time I open the mail app it does not load mail, and it just shows a blank screen. Then after 3 or 4 seconds, it closes and goes back to the home screen. My ipod is NOT jailbroken, and all the ways that seem like they could fix it on google are for jailbroken ipods. Does anybody have any idea how to fix it?
