Motorola V600

Hi, i have a contract with rogers wireless in Canada. I purchased the Motorola V600 on ebay and had it professionally unlocked. The phone is originally a t-mobile phone, and currently i can not get on the internet with the phone, i was wondering if there is any way to get all of the t-mobile default things off the phone and to be able to get on the net, thanks alot.
