It appears T-Mobile won't be able to sell Apple's new iPhone this year.
That's because the carrier uses a slightly different frequency for its cell phone signals that isn't compatible with the iPhone.
In a leaked internal memo obtained by TmoNews, T-Mobile appears to be encouraging retail employees to start "selling against" Apple's next-generation iPhone when it launches on September 21.
Translation: encourage customers to buy unlocked iPhones at full price and run them on T-Mobile instead. (T-Mobile's plans tend to be cheaper than AT&T and Verizon's, so it could be an attractive offer for some people).
Unfortunately, iPhones can only run at 2G speeds on T-Mobile's network. The carrier is working on upgrades that'll finally bring 3G/4G speeds to the iPhone, but it's only available in limited areas. The next iPhone is expected to work on LTE networks, an insanely fast wireless technology that T-Mobile won't have until 2013 at the very earliest.
