When the 2.0 beta came out a year ago the App Store icon was there but was not functional. In a later 2.0 beta they removed the App Store icon entirely due to the fact that it confused people. Then when 2.0 officially launched the App Store icon was added again.
Maybe the MMS just is not functional yet...
I hope this helps,

P.S. To anyone who has the 3.0 firmware for the iPhone 3G (especially those people whose question I just answered):
I have a question for you. Money is a little tight right now and I cannot justify joining the developer program at a hundred dollars. Several of the people in my department have been laid off and I could very well be next.
I am dying to get my hands on this new firmware. Would you mind helping out a fellow MacRumors member by sending me the new firmware? More importantly will you PLEASE add my UUID to your portal so authentication can work?
If you are willing to help please email me at:
AppleNiMac@yahoo.com
I appreciate your consideration either way...
