Okay, I'm a secondary line on a family account. The primary line gets an upgrade option after a year and I have to wait the normal two. I never understood that. Anyway, I'm just making sure I can still steal the upgrade from the primary account. It belongs to my mom, but as long as I'm still grandfathered into unlimited data, I'm never leaving the plan. Anyway, even if I can't steal the upgrade, I'm giving her my Thunderbolt even though she still lives in an area that won't see 4G till the end of 2013. So can't I just upgrade her line and then activate the new phone on my line and reactivate her old phone on her line again? That seems like a good option if they won't let me steal the upgrade. Okay, just give me a Yes or a No if this will work. Thanks guys.
