Samsung Galaxy S II ( T-Mobile)
The Samsung Galaxy S II ranks as one of T-Mobile's most powerful and feature-rich Android smartphones, but it's somewhat pricey.
Sony Ericsson Xperia Play 4G ( AT&T)
AT&T's Sony Ericsson Xperia Play 4G is ideal for gamers, but we'd prefer to see more-accurate controls, a few more features, and a faster data network.
LG Thrive ( AT&T)
The LG Thrive is a decent entry-level Android smartphone for the prepaid crowd, but its limited data plan encourages us to look elsewhere.
Third Rail System ( for iPhone 4)
The Third Rail Slim Case for iPhone 4 with Slide-on Smart Battery is arguably the best mobile juice pack on the market. It's especially useful if you also have other mobile devices.
Nokia Astound ( T-Mobile)
The Nokia Astound is a beautifully designed and affordable smartphone for T-Mobile, but there are other budget-friendly options available with better performance and that are easier to use.
Samsung Zeal SCH-u750 ( Verizon Wireless)
Fans of the Samsung Alias 2 should love the Samsung Zeal's identical convertible flip design and e-ink keyboard. However, if you're not open to a learning curve, the Zeal has little new to offer.
Samsung Continuum ( Verizon Wireless)
More than just a gimmick, the Samsung Continuum's secondary display is a useful management and multitasking tool, but its constant flow of information might not appeal to everybody.
BlackBerry Curve 8530 ( MetroPCS)
Though not the best BlackBerry on the market, the Curve 8530 is a great entry-level smartphone, especially with MetroPCS's inexpensive unlimited monthly plan.
Samsung Gravity 3 ( T-Mobile)
The Samsung Gravity 3's full QWERTY keyboard and messaging features are enough to satisfy most heavy communicators, with other advanced features icing the cake. At $50 with a two-year service agreement, the Gravity is a good midlevel option for those who aren't ready to jump into the smartphone arena.
Samsung Sunburst ( AT&T)
As long as you don't expect it to have groundbreaking performance, the Sunburst is a simple touch-screen phone with a healthy set of midrange features for a pretty good price.
