E-mail Problems...Please Help!

[SoooSmooth9]

I have had the 8350i almost since its release, and have had all my email accounts set up since day one and they always worked fine. I'm not sure when exactly I stopped recieving them threw my phone. It was almost def. after upgrading to OS 5.0 or adding a @hotmail account. The rest of the email is @yahoo. I'm not sure what cause the problems and I don't know how to fix it. Thanks.

You have to resend your service books - thats what it sounds like to me.
