I have an iPhone 8GB running firmware 1.0.2. I have set it to auto check for new mail every 15 minutes but I find that throughout the day I have to manually open the app to make it check for mail and I end up receiving mail that can be hours old. It seems my iPhone only sometimes checks for mail, not every 15 minutes like I set it to. I have restored my iPhone and have done a full reset of the phone and it has made no difference. Is anyone else having the same problem and is there any way to fix it?
