T-Mobile shakes up the mobile phone business again.   I’m Fred Fishkin with technology BootCamp, a report on gadgets and gear.     T-Mobile has become the rebel in the cell phone business.   Among the latest moves from the self proclaimed Un-carrier…  a no strings attached one week test drive of the iPhone 5S.   COO Jim Alling…

“No obligation.  No charges.  And we want people to see how great our network is.   We’ve got America’s fastest network with the best data speeds.   And a lot of people don’t realize it.  So we thought this is a great way for people to get a chance to experience.”

Even T-Mobile’s existing customers can get in on the iPhone trial.   T-Mobile is also now letting its customers stream music from a variety of services for free.  That is.. streaming music won’t eat up the data in your plan.   By the way Sprint…which is rumored to be negotiating a T-Mobile purchase…has answered T-Mobile with a free trial offer of its own.   You can find us at BootCamp.com.  I’m Fred Fishkin.
