Now that the Nexus 7 3G has been on sale for a while, there is an interesting little change. No longer does it say “Unlocked” about the device. Now it says “Unlocked + AT&T SIM,” meaning it will ship with an AT&T SIM card for no extra charge. While the N7 is also compatible with T-Mobile’s network, throwing an AT&T SIM in there, along with the big AT&T ad towards the bottom, is a pretty clever advertising idea. Plus it really doesn’t hurt anyone. What do you guys think? Leave your thoughts in a comment!
