Move over iPhone, because there's a new phone in town that just might blow you out of the water. T-Mobile's new G1, also dubbed by some as the Google Phone, hit the market on October 22, and already it promises to be iPhone's greatest rival.

The phone, which is built by HTC and is available through T-Mobile, offers features similar to those found on the iPhone. In fact, it even looks much like its competitor, although it is a little narrower, a little thicker, and has some interesting additional features. G1 offers users a convenient touch screen, navigation via a trackball, high-speed internet, email, IM, SMS texting, and Wi-Fi. In addition, there's a QWERTY keyboard that slides out for easy use and a 3.0 megapixel camera that allows for photo sharing.

Since the phone's software has been developed by Google, it's no surprise that there are many Google applications available. YouTube, Google Maps, and Gmail can all be easily used through the G1. T-Mobile's G1 is the first in a long line of phones that will feature Google's Android software. Anyone outside of the U.S. will have to wait a bit longer for the G1. Britain will see it in November, while other countries using T-Mobile will have to wait until 2009. Right now anyone in the U.S. can get a G1 for around $180 with a 2-year T-Mobile contract and plans start at $55 a month.
