Take HTC's well-received HD7 Windows Phone 7 handset, uses Super LCD to boost the display quality of the 4.3-inch 400 x 480 screen, add the finally-updated newest version of Microsoft's mobile OS [Copy! And! Paste!] and you have the HD7S: the biggest-screen WP7 handset. Due from AT&T "in the coming weeks." Don't ask yet about price.

AT&T unveiled the U.S. version of LG's Optimus 3D smartphone, relabeled the Thrill 4G. LG lets you see 3D without those pesky 3D glasses. And its rear-mounted stereoscopic 5-megapixel cam captures photos and 720p video in 3D. The Thrill runs Android 2.2 on a dual-core TI processor, has 8GB of onboard memory plus the same amount in a MicroSD card, an HDMI-out port.

The display is a 4.3-inch screen with 800 x 480 pixel resolution, which is less than the just-announced HTC EVO 3D, and can cause the Thrill's 3D images to appear grainy by comparison, according to some reviews.

Is it really 4G? It will run on HSPA+ cellular networks, but whether that will mean 14.4M or 21Mbps is unclear. You'll have to wait some months before it's available.

T-Mobile unveils the Nokia Astound, which features a 3.5-inch capacitive touch AMOLED displays, at 360 x 640 pixels. Early reviewers are impressed by the display quality.

Astound has a rather astounding 8-megapixel camera with dual-LED flash and 720p HD video capture; free turn-by-turn navigation from Nokia, and Nokia's Ovi Maps; access Nokia's Ovi Store for paid and free apps; 8GB internal memory and a MicrosSD slot for cards up to 32GB external memory.

The phone runs Nokia's Symbian 3.1 OS, which will eventually be phased out for new devices running Windows Phone 7. But right now, says PC World's Sasha Segan , who calls the Astound "T-Mobile's best feature phone," the new handset combines beautiful hardware with excellent camera, maps and navigation, fast Web browsing, for $79.99 after a $50 mail-in rebate and a two-year contract.

Samsung showed off two new Galaxy Tab models, one of them a thinner, lighter version of the Tab 10.1 unveiled just last month at Mobile World Congress. Both the new 10.1 and 8.9 models (the numbers refer to the screen sizes) are about 0.33 inches thick, comparable to iPad 2.

The other iPad similarity: pricing. For the Wi-Fi models. The Tab 10.1 in 16GB and 32GB is $499 and $599; the comparable 8.9 model is $469 and $569. They will support 4G cellular or more accurately HSPA+ up to 21Mbps.
