It might take a while before BLU Products (makers of affordable and unlocked phones for North America) comes out with Windows Phone devices like it promised. Until then, we'll likely see it launch more Android phones first -- like these four KitKat devices from its new Studio C series line. Since C stands for "color," the phones comes in different hues, with the HD version boasting the most number of variants. As its name implies, Studio 5.0 C HD has a 5.0-inch, 720 x 1080 IPS screen with a 294 ppi density. It also has an 8-megapixel rear camera, a 2-megapixel front cam and a 64GB microSD card slot. The device runs on a 1.3GHz Quad Core MT6582 processor with a 2,000 mAH battery. Next comes the Studio C Mini, which shares many of the 5.0 C HD's specs, 'cept it has a 4.7-inch 480 x 800 IPS screen, a 5-megapixel rear camera and 512MB of RAM.

The third device in the series is the Studio 5.0 C, which has a 5-inch 480 x 584 resolution screen, a 5-megapixel rear and a VGA front camera, a 32 GB microSD card slot and 512MB of RAM. It runs on a 1.3 GHz dual core MT6572 processor and a 1,800 mAH battery. If the Studio C Mini's the smaller version of the 5.0 C HD, then the 5.0 CE is the 3G-less version of the Studio 5.0 C -- in fact, it's the only phone in the line without 3G capability. Other than that and its 3.2-megapixel rear camera, it shares the 5.0 CE's spec list. All these phones come with 4GB of internal memory, dual-SIM support and, as is typical for Blu phones, they're all unlocked and work with any GSM network in the US.

You can now get the Studio 5.0 C HD ($149) and the C Mini ($119) from Amazon, while the 5.0 C and the 5.0 CE will be available soon for $109 and $89, respectively.
