The Samsung Galaxy S2 re-released on the AT&T network Nov. 6 as one of the network's first 4G LTE powered smartphones.
AT&T released the device under the variant name Skyrocket, along with the LTE version of the HTC Vivid.
The specifications of the Galaxy S2 Skyrocket LTE include a 4.5-inch display, 1.5GHz dual-core processor, Android 2.3.5, Gingerbread, 8-megapixel rear camera with 1080p HD recording, 2-megapixel front facing shooter, 16 GB of built-in storage, Wi-Fi, Bluetooth and NFC.
The Skyrocket LTE retails at $249.99 with a two-year contract and data plan.
AT&T's data plans include DataPlus that provides 200 megabytes of data for $15 per month and DataPro that provide 2 GB of data for $25 per month.
Technology Website BetaNews noted that several Galaxy S2 owners on the AT&T network might have a dilemma with the release of the Skyrocket variant.
The original AT&T Galaxy S2 released on Oct. 2, and it is now outside AT&T's 30-day return period. Galaxy S2 owners who bought their handsets a little over one month ago would have to sign a completely new contract on order to buy the Skyrocket at $249.99.
BetaNews suggested that upgrading to the LTE and HSPA+ model from the HSPA+ only model could be a worthwhile investment.
AT&T is constantly expanding its LTE availability. Besides Atlanta, Chicago, Dallas-Fort Worth, Houston and San Antonio where AT&T's LTE capability is currently available, the network introduced the service to Baltimore, Washington, D.C., Athens and Boston on Nov. 6.
The HTC Vivid retails at $199.99 with a two-year contract. Its specifications include a 4.5-inch qHD display, 1.2 GHz dual-core processor, an enhanced 8-megapixel camera with 1080p HD video recording and 16 GB of built-in storage.
