The HTC One S has landed on T-Mobile and to get customers interested, T-Mobile is offering to give anyone willing to trade-in their old Android smartphone $100 of the cost back. The offer is actually good on all of T-Mobile’s 4G phones, but since the HTC One S launched today, it’s most likely the one customers will be after.

Wirefly has discounted the price of the Verizon DROID RAZR to $49.99 for anyone willing to sign up for a new two-year contract. While I’d personally go with the Samsung Galaxy Nexus (which they are also offering for $49.99), if for some reason you’re in the market for a DROID RAZR, this is good deal. It’s on par with what Amazon Wireless is charging for the RAZR and is $50 less what you’d pay over at Verizon.

There’s a pretty sweet deal going for anyone looking to pick up an unlocked GSM Galaxy Nexus. For about 13 more hours, the Daily Steals site is offering an unlocked 16GB GSM Galaxy Nexus for the insanely low price of $459. Okay, it’s not “insanely low,” but it’s still a heck-of-a-lot cheaper than the usual $700 price tag.

Leap year comes but every four years and what better way to celebrate than with $100 off a 4G LTE device on Verizon. That’s exactly what Verizon is offering in their Leap Year Promo which will be running all day today. This deal is online only and discounts all 4G LTE devices by $100 for anyone signing up for a new 2-year contract and data plan. New customers will also be able to take advantage of Verizon’s double data promo which offers double the data allotment when you sign up for a data plan of 2GB or higher.

Now here’s a deal you won’t want to pass up. Right now, Amazon Wireless is offering the Android 4.0 packing Samsung Galaxy Nexus for the amazing price of $99. Of course this is for new 2-year contracts, but if you fit that description, here’s your chance to get the latest and greatest Android device at a ridiculous price. We’ve seen the Galaxy Nexus get discounted $50, and even $100, but never a full $200 off of what you would normally pay. Consider this your official invitation to join the Ice Cream Sandwich club.
