All sorts of data issues

Yep, Exact same problem here. The constantly spinning spinner while on the mail application is a certain indication that I am having data issues. Once I see this I know that other applications that use data (such as Pandora, etc.) will not function correctly if at all. I recently upgraded to 2.0.2 but I believe this was happening even before the upgrade.

Now I'm not saying that the mail application constantly trying is causing the problem (but maybe it is) but more likely it seems like an overall data problem causing mail and other data using applications to no function properly.

I am finding myself in this situation more frequently lately, and it usually takes several reboots to correct.

UPDATE with some more info...

I hope some Apple support staff is reading this.

I hooked my iPhone up and viewed its console logs using the iPhone Configuration Utility while it was constantly spinning on mail and having data issues.

This is what was getting logged at the time. These messages were looping over and over. BTW, I was not on wireless but had a full signal with 3G when capturing these logs.

_*BIG NOTE HERE: THE PROBLEM WENT AWAY AS SOON AS I CONNECTED TO WIFI, BUT IMMEDIATELY RETURNED ONCE BACK ON 3G!*_

It does seem like a DNS issue, which as others have noted seems to occur when transitioning between wifi and cellular.
