Product title: Lg Mytouch Q C800 Unlocked GSM Android Slider Phone - Black/purple
Product description: If you're familiar with the MyTouch Q's predecessor, the MyTouch 4G Slide, you won't find many surprises here. Also a QWERTY slider, the MyTouch Q's look and feel are very similar and it's practically the same size. Measuring 4.7 inches tall by 2.5 inches wide and 0.5 inch thick, the MyTouch Q is not small or trim by modern definitions. And tipping the scales at 5.6 ounces, the phone isn't light either. Compared with much thinner smartphones like the Samsung Galaxy S II for T-Mobile, the MyTouch Q is plump and portly. Still, I found its softly curved edges comfortable to hold, and the gray soft-touch back coating provides a sure grip and repels grease and prints. Eschewing the large 4.3-inch or even 4.5-inch panels gracing many of today's modern Android handsets, the MyTouch Q relies on a smaller 3.5-inch LCD screen. Immediately, I noticed how fuzzily the low-resolution screen (480x320 pixels) rendered details in app icons, photos, and especially text. Contrast wasn't great either, with the black background of the Android app tray, for instance, appearing grayer than it should. Viewing angles also were disappointing and tilting the device in any direction off axis quickly killed image quality. Below the screen are illuminated capacitive buttons for typical Android controls including Menu, Home, and Back. Instead of the Search key, though, there is the Genius button, represented by a circular "G" logo. Long-pressing this key, a staple of T-Mobile MyTouch devices, fires up the phone's voice command capabilities. You can tell the MyTouch Q to do simple tasks like "Send text message to John Smith, running late," or "Find the nearest espresso." The MyTouch even can be commanded by voice to launch specific applications or play favorite music, which is handy if the phone is buried deep in a pocket or bag. In my experience, the feature worked as advertised. That said, don't be fooled into thinking this is as powerful or intelligent as the Siri assistant on the iPhone 4S.
Product feature: The T-Mobile MyTouch Q offers a satisfying physical keyboard and a fast 4G data connection for people on a budget., 2G Network GSM 850 / 900 / 1800 / 1900, 3G Network HSDPA 1700 / 2100, Running the Android 2.3.4 Gingerbread OS, the MyTouch doesn't offer Google's latest version, Ice Cream Sandwich (version 4.0), but honestly neither do most current handsets, let alone most basic Android handsets. All the essential and powerful Android capabilities are here, such as Gmail, Google Maps, and access to the over 500,000 apps, not to mention movies and books, available for download from the Android Market. The phone can handle personal and corporate e-mail accounts and the usual text-messaging tasks. You tackle multimedia primarily through the simple onboard music and video software., Unlocked cell phones are compatible with GSM carriers like AT&T and T-Mobile as well as with GSM SIM cards (e.g. H20, Straight Talk, and select prepaid carriers). Unlocked cell phones will not work with CDMA Carriers like Sprint, Verizon, Boost or Virgin.
