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.

It’s been a long time coming, but the waterproof, shockproof, modular LifeProof phone cases has evolved from their iDevice origins and now protect their first Android phone, the Samsung Galaxy S3.

Two models of the LifeProof case have arrived for the Galaxy S3 this week: The Fre, the original case from LifeProof; and the Nuud, which is similar to the Fre but is free of a screen protector and allows unobstructed access to the S3’s screen. LifeProof says these cases are the thinnest and lightest fully protective cases yet made for the S3.

Earlier today, we told you about MoDaCo.SWITCH, a terrific new tool for the HTC One that allows you to install both Sense and stock Android and switch between then at the touch of a button. At the moment, it’s only available on one device, but MoDaCo has plans to bring it to the Galaxy S4 (i9505) in the near future.

If you’d like to see that happen, here’s how you can make a pledge to support its development.

British retailer Phones 4U has today launched a new Arctic Blue variant of the Samsung Galaxy S4. It’s available on contract only, with prices starting at £37 ($57) per month if you want to pay nothing upfront for the handset itself. The handset also comes with a free Samsung S-View case.

Sony has today revealed its Android 4.3 upgrade plans for Xperia smartphones and tablets. It’s good news if you own an Xperia Z or one of its many variants, as well as the Xperia SP — all of which will get Android 4.3 at some point. Sony also says it is looking at “uplifting some of our other devices running 4.1 direct to 4.3.”
