Long delay before mail received sound

Question

When I check my mail it may take nearly two minutes before the mail sound chimes after mail is received. For example, today when checking mail I got one short email. I saw the white progress bar at the bottom of the screen and the message that Mail was downloading one email. It was almost a full two minutes after that before the the mail sound chimed and the spinning wheel at the top of the page stopped. I usually have time to download, read and discard my email before the mail chime sounds. This was never the case on my 3GS running iOS 3. I now have the iPhone 4 running iOS 4.0.2. Is anyone else experiencing this problem? Is Apple aware of it? Is this a known issue? Is there a fix? Thanks.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you boot, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal boot may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, reboot as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.
