Neither of those come with a HSDPA radio chip on them tho, nor any off the sensors and such that one expect in a smartphone. The GTA04 is a single board smartphone, that i think i theory could be used as the basis for any number of open device if one could source a appropriate screen (not sure how flexible things are there in contrast to the desktop world), case (tho Shapeways and other 3d printing services may help there) and battery.
