I've had my email account hooked up to my jail-broken iPhone 4 before, and today it seemed to stop pushing my emails. So I did what I normally do when it seems like this happens- I deleted the account from my phone and went to go add it again. When I went to add it, it wont let me now. It says "username and/or password" is invalid or "apple.imap....(somthing) wont connect". Please help if you can.
