The Samsung Galaxy S II Skyrocket ($149.99) is a big slab of Android, but with a twist: It’s one of the first two smartphones to support AT&T’s brand new 4G LTE network, the other being the HTC Vivid ($99.99, 4 stars). We’re giving the Editors’ Choice nod to the Skyrocket, thanks to its faster performance, lightweight design, and vibrant (if not as high resolution) screen, but the Vivid is also a very powerful smartphone—you can’t go wrong with either one.

Design, Screen, and Call Quality
The Skyrocket looks a lot like the Galaxy S II ($99.99, 4.5 stars). It features a matte, slightly textured back panel, black glossy plastic sides. It measures 5.15 by 2.75 by 0.37 inches (HWD) and weighs 4.65 ounces. At least, that’s what Samsung and AT&T both claim. But if you lay the Skyrocket flat on a table and place a ruler next to it like I did, you’ll find it’s actually about 0.42 inches deep. It sticks up noticeably higher than an iPhone 4 I had nearby (which rings in exactly at its quoted 0.37 inch figure). The Skyrocket is still thinner than other LTE devices we’ve tested, though, and it’s certainly lighter in weight.
