iOS 4.01 "Checking for mail"

Hi Saumil.
I have the same problem than you exactly from the IOS 4.0 update. Sorry but after 4.0.1 the problem are still there, because the reason for it are the multitask... with this new possibility in the new 4.0 the Mail application are currently open and searchin for new messages continously...

Exist a new notice for me.... If your mail server are empty of messages the iphone after a few seconds stop the sync. But if you have only one message in your mail server, your Iphone will be sync during hours until the end of your batery.
Do you know if someone have our same problem? An solutions?
Thanks and best regards.

I ma having the same problem. I have three email accounts (one exchange)and it happens at once with all of them. Could not figure out why it starts. Everything works fine after rebooting for a while and then all of a sudden when want to check my new messages in the inbox (any of accounts) it stucks and the sign keeps spinning endlessly. A turnoff/on is necessary to make it work again. several times per day.Frustrating,

I restored the phone went up to 4.0.1, deleted all accounts and reinstalled them, but did not help at all.

I think I just solved the problem myself. Try this, go to settings/mail/ fetch new data push/ turn push on/ at the bottom of the page go to advanced and change everything to fetch. worked for me. remember I have already restored, deleted and reinstalled as per my previous post.

Hi to all.
Some days ago I change to fetch and it was not a solution for my problem.
After too may changes in my Mail application, I´m absolutely sure that the only situation where Mail stop the sync is when my mail server has any new or old mail.
I´ve two mail accounts, one is a POP account (hotmail) and another one is an IMAP account. Exist some post in this forum talking about the possibility that this is the real reason of the problem.....
Thanks to all for your help.
Best regards.

Thanks. My situation was slightly different, a 3g which had recently updated to IOS 4.1. Suddenly this evening, the mail app starting spinning aimlessly as the app allegedly searched for email. (Initially, it showed how many emails there were and how many unread, but showed no emails or synopses; but after reboots, it didn't even show even that.) I went into mail settings and turned push off and in mail settings/fetch new data/advanced set each account from fetch to manual. I immediately reset push on and and each account back to fetch. Miraculously, when I opened mail this time, there were the email listings as if they had already been loaded.

I don't know whether this is another by-product of the buggy IOS or something completely different.

At any rate this was my wife's iPhone. I am waiting with my identical iPhone to upgrade the IOS until Apple makes patches (including on the wonky calendar) or I give in.
