Earlier today Sprint announced April 12th preorders for the LG Viper 4G, one of its first LTE devices to come to market. Sprint's renowned for being one of the few to still offer unlimited data on its WiMAX network, and TechHog noticed that Sprint's press release contains the phrase "pairing innovative technology with the Sprint 4G LTE network and unlimited data plans, LG Viper 4G LTE..." essentially confirming that the unlimited trend would continue on LTE. After they posted their findings, TechHog got a response from Sprint's PR department confirming that, yes, the Viper 4G LTE "will be available on Sprint's network featuring unlimited data." So there you go; if you're a heavy data user, Sprint's unlimited plan will offer reams more data (infinitely more?) than the top 5GB and 8GB plans offered by ATT and Verizon, respectively, but what really matters is whether or not the company will have LTE in your area when it begins rolling out its 4G service.
