iPhone 2.1 Does Not Play Fetch
Have you noticed that your email doesn't seem to update when your iPhone is locked and asleep? It is not just you. It seems for a lot of users
iPhone firmware 2.1 does not fetch mail while it is sleeping. This bug was probably introduced with the power saving features added in firmware 2.1 that are intended to save power - checking your email all the time takes up quite a bit of iPhone power - but with this bug apparently kill function. Will this be fixed in firmware 2.2? We can only hope.
Note: While plugged in it should work normally. This problem seems to only occurs under battery power.
