General Jelly Bean update

Finally Samsung started rolling out the Jelly Bean update for the tab2 10.1 but here's the thing. My sis, who has the exact same model, did get an update to Jelly Bean (4.1.2) and I didn't. She had a slightly newer version of Android (4.0.4) than me (4.0.3) but I thought the update would cover ALL tab 2 10.1s so what's the deal? Am I screwed out of an update or just not patient enough?
