I've set up Gmail according to their instructions, enabled IMAP on my account, etc etc - almost every time I ask it to check for mail, I get: "Cannot Get Mail The connection to the server "(null)" failed." A couple times a day it will pull mail correctly, but most of the time I get this message. It's also done weird things like when I type a new message (either on the iPhone OR in Mail), it "sends" but then is nonexistent in my sent box on the phone/Mail and in Gmail. The message never actually sends...but I get a message saying it sent. Is anyone else having weird problems like this? Any solutions?
