it's known on AT&T, recently joined the herd of others cluttering up the carrier's shelves after being known elsewhere for the longest time as the SGH-i907. For those teetering on a purchase, the cats at Pocketnow have some valuable insight you should probably chew on first. For starters, they found the screen to be stout and the optical joystick to be "fantastic," though the dearth of in-box amenities was a bit of a letdown. On a very positive note, the reviewer never once had to initiate a soft reboot, and the ginormous 1800mAh battery got him through a solid 1.5 days of heavy usage before calling it quits. Unfortunately, the lackluster software suite was the Achilles' heel; critics found that Samsung's Windows Mobile overlays and additions were ho hum at best, and the complete omission of a soft reset hole was just unacceptable. The bottom line? You should probably give this one a handle in-store before buying blind -- as lovely as some aspects are, you don't want to buy into a device that's frustrating to use.
