The sign-up page for the Samsung Galaxy S III has gone live, allowing users to register for up-to-date information (for before-the-date information follow an Android blog such as CoA) regarding the Samsung Galaxy S III U.S. launch. It’s interesting to see all major and regional carriers listed under the “carrier preference” drop-down menu and this indicates Samsung plans to bring the Galaxy S III to as many U.S. carriers as possible. Whether or not these carriers will feature the device, and at what dates, remains anyone’s guess — although Samsung did say it would hit the U.S. sometime in the summer.

Google announced it will be extending carrier billing services to include all types of content on Google Play. Carrier billing is a “convenient” way to charge digital content directly to your carrier phone bill versus having to use a credit card or separate payment method. While it can be seen as more convenient, it’s also a dangerous road to go down. Our phone bills are already mini-car payments and adding digital content purchases to it can result in astronomical monthly bills.

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.

Just about every major carrier seems to boast the “fastest network speeds,” while bombarding us with acronyms like LTE and buzzwords such as “lightning fast.” When it’s all said and done, we’re left confused and none the closer to the truth of which network actually has the fastest speeds. So how do we find out the truth? Well, it’s not as simple as we’d like it to be and there are near infinite variables to the equation, but one way to get a general idea of how fast a network’s speeds will be in a real-world environment is to test them out.

T-Mobile has pretty much fallen off the face of the mobile earth ever since its failed marriage to AT&T. They’ve been pretty quiet since then and really haven’t wowed us with any new devices or announcements. The next “big” thing to hit T-Mobile is the HTC One S, which really isn’t that “big” of a deal. In an attempt to sell the One S to its customers as well as attempt a complete rebrand, T-Mobile will be unleashing the alter ego of Carly, the innocent girl in the magenta dress you’re used to seeing in those T-Mobile commercials.
