Leading the pack of music phones is the Nokia 5310 XpressMusic, considered as the most pocket friendly music phone in the market. It is one of the slimmest mobile phones currently available with dimensions only a hair bigger than the iPod Nano and weighing only 3 ounces. It offers a bright 2-inch QVGA display and the keyboard is spaced just right. To listen to music, you can either go wired with the 3.5mm headphone jack or wireless via stereo Bluetooth. The 2-megapixel camera packs some punch as well, doing a solid job of taking pictures in daylight conditions. Though the phone doesn’t offer 3G or Wi-Fi, Internet browsing is made possible through T-Mobile’s EDGE network. The reviewer stated that call quality is good over T-Mobile’s network. Battery test results went reasonably well, holding up for 3 whole days even with frequent music usage. If you are in the market for a music phone, the sleek Nokia 5310 XpressMusic will surely impress you.
