Verizon's version will be called Samsung Fascinate. It will come with a 16GB microSD card included, 3G mobile hotspot functionality, and the carrier's usual slate of branded features such as VZ Navigator and V Cast Music. On T-Mobile's network the Galaxy S will be called Samsung Vibrant and includes a 2GB microSD card preloaded with the movie Avatar and The Sims 3. T-Mobile will start selling the Samsung Vibrant from July 21, for $199 with a two-year contract.
Over on AT&T the phone will be called Samsung Captivate, including 16GB of storage and various customized features such as AT&T Navigator and AT&T Address Book. Last but certainly not least, Sprint's version of the Galaxy S will pack a few extra surprises. Dubbed Epic 4G, the device will be able to hop on Sprint's WiMAX network for faster download speeds (where available), and adds a slide-out QWERTY keyboard, six-axis sensor as well as a front-facing camera.
The device will be Sprint's second WiMAX phone and is a great alternative to the HTC Evo 4G if you just can't get used to software based keypads. Common to all editions of Samsung's Galaxy S is version 2.1 of Google Android, with 2.2 "Froyo" upgrades expected to come at a later time.
