I don't know what happened. But for some reaon the back button has dissappeared from my email. So now I can't get into my inbox. The only way to see my other message is to delete the message I'm currently looking at. Can anyone help me fix it.
Maybe you need to get a Doctor to check out your 'male problem'. only joking, lol. Are you using a jailbroken device? I can't understand how/why the back button would disappear. Try re-booting your device (hold home and lock buttons together until phone restarts to Apple logo screen). You can always go through your messages using the arrows on the top right corner. You don't have to delete any messages.
go to settings and delete your email account>open mail>close mail>open settings>add account (add your previouse account). should fix.
i wish i knew what i did but its fixed now. I just turned off the itouch and back on and the mail was normal again.
