Hey guys, I was wondering if anyone has had this issue. I got my iPhone 4S replaced over the weekend due to a defective speaker. And when I got home, I installed 5.1.1 on it, jailbroke it and restored from my backup. Since then, my iCloud mail isn't pushing new mail anymore. I've tried deleting the account from the phone, then putting it back, and the push will work. But then after about 2 hours, I get nothing unless I open the mail app. My other Yahoo account pushes mail with no issues. I'm not new to jailbreaking, but I've never had this problem before. Any advice?
