Can't access T-Mobile data network

[philhenley1]

I'm on an unlocked 2g iPhone w/ 3.0 software on T-mobile's network. The problem is that anytime I try to access the internet I get the message:

"could not activate cellular data network: You are not subscribed to a cellular data service"

I have the Blackberry unlimited data plan through T-mobile. And if I put my SIM back in the BB, I can jump right on the internet with no problems.

I've tried the following APN's on the iPhone:

epc.tmobile.com
internet2.voicestream.com
internet3.voicestream.com
wap.voicestream.com
hiptop.t-mobile.com

all with blank username and passwords. None of them work. The "E" shows up on the phone, so it looks like it is at least on the Edge network.

Anyone have any ideas why I can't access the data network?

Do I need to get a different data plan through T-mobile?


Thanks

Thanks for the help.

I ended up just going into the T Mobile store and telling them what I was trying to do. They were cool about it and said I need to go to a plan that wasn't BlackBerry specific. So I switched to the smartphone plan and everything is working now.

Here is how they set my phone in case anyone else is interested:

data roaming = on (they said they don't charge for data roaming unless it is international roaming)
