It appears that T-Mobile US parent company, Deutsche Telekom, brokered a deal with Apple that will see T-Mobile carry and sell Apple products in 2013. The writing was on the wall, as this was the last of the four major US carriers to carry the iconic iPhone and iPad. The news is still developing and Apple has yet made any public announcements.

Of course, the only Apple "products" that T-Mobile would sell would be the iPhone and iPad.
