The competition in the smartphone industry is increasing rapidly and so is the rivalry between the carriers. To stay ahead in the race, U.S. carrier T-Mobile has an array of top-end smartphones on offer to lure more customers to the network.

Rumors of the upcoming smartphones, including the next-generation iPhone and Galaxy S4, are circling the smartphone market, but for those who don't want to wait and are looking up for a top-end smartphone, T-Mobile's offers may be right up your alley.

Take a look at the top five smartphones from T-Mobile:

Nexus 4
Google, in collaboration with LG, released the Nexus 4 in November 2012 and T-Mobile started selling the smartphone from Nov. 14. Strong-demand for the handset saw the Nexus 4 sold out on many occasions on the network.
