Nope, but I'm on the look out for it. Really hope Verizon will do something similar. The 1GB per device promotion is a joke compare to ATT's new promotion.
I wish they'd double my 2GB single line plan, but I don't see that happening lol. They could introduce something in the coming weeks, but they already have their +1GB for 2 years on any MORE Everything plan promo going on right now.
