Im unable to get my data working on 2G iPhone.

I switched over to a Galaxy.Never switched my data plan.But just didnt like the phone so switched back to my 2G iPhone.

My-tmobile.com shows my old nokia which is a web2go phone.Web2go works perfectly fine on that phone still.

Anytime I get on safari I get the tmobile upsell page.saying to continue for 1.99 a mb click here...Obviously I dont click it.

I have tried epc.tmobile.com, wap.voicestream.com & internet2.voicestream.com & none are working.

Any takers?
