I was in a cell phone store today asking about the Treo 650. The rep told me Edge is coming to T-Mobile in the 1st Quarter of 2005, and that T-Mobile already signed the Edge contract with At&t to use the Edge equipment.
The rep then told me he was on T-Mobile and showed me his new Edge-capable phone he just bought in anticipation of Edge capibility. He then explained that Edge would not be covered by the $19.99 internet plan.
