In T-Mobile USA’s first earnings report since the proposed merger with AT&T fell through in December, it noted a loss of 802,000 customers in Q4 (being the only carrier not to have the iPhone is a lonely, lonely circumstance). But there is some good news — thanks to the AWS spectrum it’s receiving due to the termination of said deal, it plans to launch LTE services in 2013. Additionally, it plans to spend $4 billion rolling out HSPA+3G/4G services on the 1900 MHz band which should mean high speed data access (in some areas) for previously unsupported devices like the iPhone 4/4S. Also, since both T-Mobile and AT&T use AWS spectrum for LTE, we could see existing (and future) unlocked devices that are compatible with both networks. For now, T-Mobile is focusing on the new devices it’s delivering like the just-announced Samsung Galaxy S Blaze 4G, and its addition of 276,000 prepaid customers. Check out the full report with all the details and dollar amounts after the break.
