So I have an iphone 4 (jailbroken with 4.2.1) and an ipad2 (jailbroken with 4.x.x) and last week my yahoo mail accounts stopped downloading new messages. The accounts are able to send emails fine, just not receive new emails. The date at which it stopped is the same on both IOS devices. I have about 4 different accounts and its impacting all of them. This is what I've tried so far: I have removed the accounts from the iphone/ipad and setup again. It verifies the account settings OK but no new emails. Changed the password to an incorrect one and it recognizes the bad password until I correct it. I have deleted extra emails from my accounts. Reboot & shutdown each device. I'd rather not reset the devices since I'm waiting for IOS5 to be jailbroken for each. Any ideas? It's odd that the problem is exactly the same for two different devices.
