Firts let me apoligize if this has already been brought up in the forum, then I'm sorry for the repeat question. I currently work for sprint and was asked a question that I couldn't answer about t-mobile's voip service. My customer was switching to sprint (she recently moved to the outer edge of town and her t-mobile just doesn't cover there) but wanted to know if sprint was offering the voip service that she has with her t-mobile.

I had heard that they had a service that they were going to start where you could plug your cell phone into a box connected to your high speed and have unlimited calls with you t-mobile number through the voip service with no overage. Is this out already? I hadn't heard.

Thanks for any info.
