I recently jailbroke and unlocked my iPhone 3g running 3.1.2 using blackra1n and unlocked it with blacksn0w. I am using AT&T but I wanted to unlock it so that if I ever had to use it with T-Mobile. Recently, my mail app has been acting a little bit funky. It doesn't connect to the server sometimes and when I send an email while on the phone, sometimes it ends the call and says called failed. It shows no service for a minute and service is restored. Sometimes during the call it just fails and I have to wait another minute. I have searched all throughout MR and I have not found anyone have similar issues. The only similar issue is with wifi and my wifi works great. Just sometimes it doesn't connect and the signal is weak. I have done a network reset and it is still messed up. I was reading about the mail app issue and some people said to go to google.com/accounts/displayunlockcaptcha and it will allow IMAP to work again. That seemed to work so far. Does anyone have this problem? Is this a known problem? Or is this just some bug? Thanks in advance.
