The Samsung Galaxy S4 Developer Edition that runs on Verizon is now available directly from Samsung for $649.99. The Developer Edition of the S4 comes with an unlockable bootloader, meaning that you will have an open gateway into the system, which is great should hacking, rooting and using custom ROM’s be your thing.

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.

A Samsung insider has reportedly confirmed that the Galaxy Note III will enter mass production this August ahead of a third quarter release. As a result, they said suppliers are less likely to feel the reduction in Galaxy S4 orders in July, which is said to be as much as 20-30%.

At Samsung’s Premiere London event, the manufacturer rolled out five new colors of the Galaxy S4, including Blue Arctic, Purple Mirage, Red Aurora, Brown Autumn, and Pink Twilight — all of which can all be seen in the picture above.
