Connecting to Internet via ActiveSync

I am adding fuctionality to allow registration of scores to our webpage from my game Beshaped.
Today Beshaped generates a code that can be registered on a jsp page.
I have added to Beshaped the functionality to contact this jsp page and register the code via Internet.
I was told that with PocketPC 2002 came the possibility to connect to Internet via ActiveSync. So I tested Beshaped with a device running Pocket PC 2002 and everything worked fine. For some reason I also tested it on a device running Pocket PC 2000 and to my suprise this also worked! So I am now thinking that maybe this have something to do with what version of ActiveSync that is running on the PC.
It does not however seem possible to use Internet Explorer via ActiveSync on my Pocket PC 2000 device.
So could anyone tell me what is required in order to connect to the Internet via ActiveSync.
