Sprint has launched a handful of new Android-powered smartphones today, including Google’s brand new Nexus 5, the LG G2, the Samsung Galaxy S4 mini, and the Samsung Galaxy Mega. All four devices are available online and in Sprint stores.

T-Mobile U.S. is now accepting pre-orders for Google’s latest flagship smartphone, the Nexus 5, on its official website. As expected, the handset’s total pricing is pretty similar to other operators on the market, however, T-Mobile is the only carrier to offer the device with a $41.99 down payment, followed by 24 monthly payments of $17, which adds up to a rather hefty $449.

Google Play isn’t the only place where you can pick up the new Nexus 5 without a contract, but if you decide to shop elsewhere, you’re likely to pay a lot more for it. In the U.K., for example, the 16GB variant costs £299 ($481) direct from Google, but some stores are charging as much as £400 ($643).

This isn’t just a bid to make a quick buck while the handset is sold out on Google Play. The reason for these high prices is that the cost of the Nexus 5 on Google Play actually undercuts the prices retailers must pay to wholesalers.

T-Mobile is gearing up to launch Google’s new Nexus 5 smartphone on November 20, according to a leaked document that details its retail plans for next month. The carrier will also launch the Nexus 7 tablet on the same day, and both devices will be available to purchase in-store and online.

The Nexus 5, as its name suggests, is the fifth smartphone to be born into the Nexus family, and by far the most powerful. Its 2.3GHz Snapdragon 800 processor, 1080p display, and 2GB of RAM make it a big improvement over even last year’s Nexus 4.

So how far have Nexus smartphones come since the original HTC-built Nexus One made its debut back in January 2010? Check out the video below for an entertaining speed test between every Nexus smartphone ever built.
