Well I was told by Tmobile sales reps that if you had a smart phone PDA, like BB, G1 and so on, that the internet plan was required $25 a month (i think)... that you couldn't get it with out it. BUT I purchased one of my BB online and wasn't asked to add or added the plan. So we got a BB with no internet plan and have wifi so we can use it online any way just not on the road... Its confusing...
