Despite all of the buzz about a potential merger with Sprint, T-Mobile is wisely pressing forward as if nothing has changed. They are reportedly still planning on pouring more pressure on AT&T and Verizon by offering up improvements to their Uncarrier initiative. According to the latest rumint, T-Mo's 5.0 phase for Uncarrier could include phone unlocking and some form of next-gen billing.
Obviously it's easy to get excited about a phone unlocking program, but the next-gen billing doesn't sound too shabby either. This "next-gen" billing will simply include all the fees and taxes into one simplified price. For example, if they offered a $50 plan, that's the price you would actually pay for the service.
What an intriguing idea!
