I have a 16GB iPhone 3G, with the latest 3.0.1 software on it. The phone is not jailbroken.

All Internet access seems to be working fine; Safari works, all my news apps work, any other app that needs to access the Internet works, Mail works, etc...I can even open the App Store and browse the Featured, Categories, Top 25, and Search sections just fine. However, when I click on Updates, it just sits there, saying "Loading..." until an error message pops up, saying, "Cannot connect to iTunes Store". If I turn off WiFi, the Updates section of the App Store will load just fine over 3G or Edge.

Here's the interesting part: if I change the MTU on my router from 1500 to 1492, I can load the "Updates" section just fine. But then some sites have trouble loading on my Mac Pro that is connected directly to the router. My Mac Pro, MacBook Air, Mac mini, Dell XPS 410, Dell Mini 9, and Palm Pre all have no troubles with the router MTU set to 1500. And my iPhone, as I said above, has no issues, EXCEPT for just the Updates section of the App Store. The Mac Pro, and MacBook Air have just had a clean install [not an upgrade] done of Snow Leopard, and the two Dells have had clean installs of Windows 7. My Mac mini is running Leopard 10.5.8.

Does anyone have any idea as to why ONLY the "Updates" section of the App Store would not work on my iPhone when everything else on the iPhone and on my network function just fine?

Oh, and in case you're wondering, yes, I have tried forgetting my WiFi network, turned off the phone, turned it back on, and rejoined the network. I have also tried doing a restore of my iPhone. The issue still persists.

Thanks in advance!
