RCS is designed as the (eventual) successor to SMS and MMS, but it's a bit of a mess right now. Several carriers have their own implementations of the standard, often incompatible with each other. Google's Jibe RCS Cloud is quickly gaining ground, but there's still only one US carrier supporting it - Sprint. Now Samsung has announced its own RCS cloud.
Samsung only made official the Galaxy Note 10.1 last night, but the company has already started releasing kernel source code to its Open Source Developer's Center.
In this case, there are two different versions of the source code available, for model numbers SHW-M480K and SHW-M480S. At first blush it's nearly impossible to cite the differences between the two, but after a bit of digging it looks like these are both carrier-connected 3G versions of the device. The "K" model appears to be for the Korea Telecom (usually just referred to as "KT") branded version and the "S" model applies to the Southern Korean Telecom variant.
We've seen a few big things come out of the IFA conference already, but none quite so awesome as the SpiderPad from Korean Telecom. This thing is an absolute beast, but not because of its hardware specs (which are quite good), but because of its accessories.
From a hardware standpoint, it is pretty impressive, rocking a 4.5-inch display, 1.5GHz dual-core proccessor, 1GB RAM, and 16GB of internal storage, along with microHDMI and microUSB ports. What really makes this little beauty amazing, though, is the fact that it can basically become a tablet, gaming system, and laptop using accessories. Have a look:
This is exactlywhat Android users have been asking for since the Motorola Atrix was first announced -- a device that can literally do it all.
