I ordered mine from DX and it does have a big lump where the chip sticks up. Where the contacts are and when you take out the memory card the little bit of PCB that you can see is black. I also just upgraded from an R4, it would still play pretty much everything I wanted it to with a little patching, but it was time for a change. I wanted just an AK 2.1 but everywhere I checked was out so I went ahead and ordered the 2i. I am still trying to find any reference of anymore like the one I got, but have had no luck.
Well, with a headlamp and my jewelers loop, I was able to see that my card is spring loaded but it was stuck down, but with some fine manipulation I got it to spring up and now it seems to be working just fine.
