AT&T 4G Micro SIMs Arrived. 4G iPhone On Its Way? [video]

This just in… our AT&T contact dropped these pictures into our inbox. Apparently they just received a new stack of 4G SIMs and one of the packs is a bundle of… micro SIMs.

Now, was this a mistake? Did they get mixed-up? Or, this just signals the fact that the next gen iPhone will be 4G compatible?

PS: barcodes and serial numbers were blurred out for obvious reasons ( and we know it’s not the prettiest thing in the world )
