I am getting the "ping" sound but I cannot see the mail. It will not load them. And the same thing was happening on my iPhone. I went to the iPhone forum and someone said that Google's servers are SUPER BUSY with the new iPhone OS 4 release and that is causing the problems. But before I knew that I deleted my Gmail account from both devices thinking I would just re-add them using the same method. No go! The servers are too busy for that. So I restored my iPad from last night's back-up and it's fine...meaning it cannot get mail but it still gets the pings. I'm hoping it really is busy servers and it will fix itself later. My iPhone however, I updated to 4.0 so I don't want to do a restore there. Right now it has no e-mail account set up because again, the servers are to busy to do it. Anyone else having problems?
