1.1.3 jailbroken iPod touch. everything else works including safari. all the latest software updates. have yahoo and gmail setup with corect passwords. for both accounts, when i click the mail icon it just sits there saying "checking for mail" and never brings up new messages in my inbox. any idea as to what happened? the app used to work fine, but out of the blue it stopped working. this was feb 1st. that it stopped grabbing new messages and stuck on the "checking for mail" thing.
