So, I had my iPhone 3G S on preorder and it was delivered on June 19th. I was out of town until tonight, and I tried to activate it. Of course, I got the 48 hours message (but received no email about any iTunes credit of any kind). Either way, my first gen iPhone continues to make calls, but no data. I cannot activate edge because I constantly get the message: "Could not activate cellular network: you are not subscribed to a cellular data service". I've been getting this message since at least Saturday, but it may have been before. I have been out of town on a college campus, so I was using WiFi almost all of the time...I didn't notice it until Saturday. This is strange, because I have always had the old standard $20.00 data plan for my first gen iPhone, never had any problems. I selected a data plan for my new iPhone 3G S when I purchased it via the Apple Store. I checked my plan online, and sure enough, it shows that I have a first gen iPhone and no data plan selected. Quite strange! I decided to take my SIM card out of my first gen iPhone and put it into my 3G S to see if the data would work in it. This did not work, I still get the same error message. Of course, the 3G S will make calls etc... with the activated SIM card. Has anyone else experienced this issue? I have tried resetting the network settings to no avail. I feel sure this is an AT&T issue, but I was just curious if anyone else had the same issue and I also wonder if it was resolved when the 3G S was activated. Thanks!
