Tonight T-Mobile held its big Un-carrier 5.0 event in Seattle, but the gathering ended up being even bigger than we originally anticipated. Not only did John Legere and Co. introduce us to Un-carrier 5.0, they also took the wraps off of Un-carrier 6.0!

First up, we’ve got Un-carrier 5.0 and the iPhone 5s “Test Drive.” As part of its new program, T-Mobile will let customers try an iPhone 5s with unlimited domestic usage for a full 7 days. After the trial is up, customers can return the iPhone to a T-Mobile store and pay nothing for their trial.

So what’s the catch, you ask? Well, there is a bit of fine print worth mentioning. When you sign up for a Test Drive, T-Mobile will place a $699.99 hold on your credit card. If you return the iPhone 5s with a cracked screen or water damage, you’ll need to pony up $100. And if you decide not to return the iPhone at all, you’ll be charged $700 for the unit.

T-Mo’s Un-carrier 5.0 move also includes some big network news. T-Mobile has activated its Wideband LTE network in 16 markets across the U.S., giving those lucky Magenta Army members access to a network with peak download speeds of 150Mbps. The current list of Wideband LTE markets as follows:

Detroit, MI
Honolulu, HI
Houston, TX

Los Angeles, CA
Minneapolis, MN
