yesterday i bought 2 ipad air, and both has different model number, one ends with A and other with B

I also notice the box cover is slightly different, the B has a white background on the ipad screen,the A has a black background.

Also B and A has different font

anyone know if the HW is also different?

Thanks.

Not aware of any differences. A change from "/A" to "/B" in Apple's model number typically signifies a minor hardware revision.
