"Sprint has no current plans to change our commitment to provide new and existing customers with unlimited data with the arrival of LTE smartphone devices this year."
That echoed earlier information for a specific device, Sprint's recently announced 4G LTE LG Viper which becomes available for pre-orders on April l2. The press release for that device quietly confirmed unlimited data, as well, by saying:
The LG Viper is a very inexpensive LTE device, and will sell for $99 with a two-year agreement.
Sprint has announced the first six markets to receive its 4G LTE by mid-year: Atlanta, Baltimore, Dallas, Houston, Kansas City and San Antonio.
It's expected that the iPhone 5 will sport LTE support, so it is important that Sprint's LTE network be up, running, and expanding by then. As the current iPhone does not support WiMax, the carrier's iPhone, along with Verizon's is relegated to slow CDMA service (when compared to AT&T's HSPA+).
Sprint's unlimited data service continues to be a selling point for the company. Although AT&T and Verizon have users with "grandfathered" unlimited data plans, both of those carriers will throttle their service when necessary.
