"you are not subscribed to a cellular data service"
i get this message when trying to use safari or ithe app store, i havea blackberry plan and i usually switch back and fourth between the iphone and the BB it usually always works. Why is this happening?

Did you upgrade to 3.1.2? Because that happened to my prepaid phone when I did. Can't go online anymore. I believe it is because the the Blackberry package uses the wap.cingular APN like the regular data plan does and the iPhone data plan has its own APN.

just find the APN settings for your carrier and add them under settings/general/network/cellular data network

The iPhone also uses wap.cingular for its APN as well, so that definitely isn't the problem. But I did notice that it started to happen after I went to 3.1.2. 3.0.1 did not have that problem at all.
