Looking to buy an Ideos S7 Slim or MediaPad (Specifically the S7-202u or S7-302u)

[phoenixrising27]

So apparently there are several models of the S7 Slim and mediapad. I'm looking to buy the S7-202u Model (Which has full phone functionality, quad band GSM, and uses U.S UMTS frequencies 850/1900/2100mhz[AT&T]) or the MediaPad model S7-302u to replace my original S7 tablet as my primary phone. I'm NOT looking for the springboard! I've been looking everywhere for it and can't seem to find one. I've found a few manufacturers on Alibaba and one site called Ren-Ben which seems to have them for order but I cannot confirm that I can get the 202u or 302u from either. Does anyone know of somewhere I could possibly get the 202u? Or if the S7 Slim goes by any different names? Thanks.
