Hello I am going to buy a blackberry curve 8900 soon from my friend and i wanted to know if it was possible to use aim on the blackberry by using the 15 dollar unlimited t mobile plan? I know the answer is no by the t mobile representatives, but I am wondering if there are any loopholes where I can. They said that the blackberry requires a web service which is not included in this plan. All i need is aim and/ or text mostly aim.

AIM, nope, not on a generic data plan. Sorry.
