I recently switched from AT&T (3gs) to Verizon (iPhone 4). Great service but since then, my home computer doesn't receive any mail unless my iPhone 4 is turned off. I've called the internet/mail provider (charter.net), spoke to Apple twice and no one seems to know why this is happening. This wasn't an issue with AT&T. I backed up my iphone and did a complete restore, turned off my computer & iphone ~ no luck;(. MobileMe email isn't affected by this. Does anyone have any suggestions as to why this happening? Thank you!
