T-Mobile’s new summer smartphone promotion is a scorcher: The carrier has eliminated down payments entirely and dropped the price of all devices to $0. Even the latest handsets like the iPhone 5, the Samsung Galaxy S4 and the Sony Xperia Z are included in the hot new deal, which the company announced today.

But there is a catch.

While the iPhone has been slowly making its way to carriers all over the world since its release in 2007, there are still a number of major operators that are yet to offer it. One of those is China Mobile, the world’s largest carrier with over 800 million subscribers; and another is DoCoMo, a Japanese carrier that serves almost half of the country’s mobile market.

But DoCoMo isn’t at all concerned, even though it’s losing customers to other carriers that do offer Apple’s device. A company executive has acknowledged that the iPhone is an “attractive” device, but points out that it also comes with some disadvantages, and insists that the latest Android-powered offerings are just as good.

The iPhone 5 has been branded the “slowest smartphone” by Which? magazine after going up against its latest rivals in a group of tests that evaluate processing power and graphics capabilities. The Galaxy S4, Samsung’s latest Android-powered flagship, came out top in the tests, with a rating almost double that of the iPhone’s.

Nokia has this morning announced its new Lumia 925, a Windows Phone smartphone with an aluminum frame that hopes to step up Nokia’s fight against Apple and Samsung. But does the Lumia 925 really have what it takes to compete with the iPhone 5, the Galaxy S4, the HTC One, and other high-end smartphones?

We’ve put together a spec-by-spec comparison to help you decide whether Nokia’s new flagship is worth the switch to Windows Phone.

So the Consumer Electronics Show is over for another year, and for those who’ve been in Las Vegas covering it for us, it’s back to normality. While we allow the Cult of Mac team to sober up, it’s time to look back at the best gizmos CES had to offer. There were thousands of products on show — far too many to cover in one week — but there were a handful that really stood out.

We’ve put together a list of awesome things that we were blown away by, including smartphones, accessories, gadgets, and more. Check it out and tell us what you’re most looking forward to getting your hands on in 2013.

LAS VEGAS, CES 2013 – It’s pretty unusual to see a major headset manufacturer’s brand-spanking new flagship phone soaking in a goldfish bowl. Then again, if that phone is the new waterproof Sony Xperia Z, maybe a fishbowl is exactly where one would expect to find it.
