Mail in Rebate for sprint Question

[rdcrds]

Ok i have 2 TP2's that i got on 2 of my 7 lines that were ready for a 2 year upgrade.So i ordered the 2 of them and got them.Now when i got the 2 of them i put them on different lines that were not ready to be upgraded yet.

I have done this before and got the mail in rebate back.But which phone numbers do i list? if i list the ones they are on now they wil mess up the rebate status on them right? i do not want to mess them up as they are ready in another month if i need to.So which ones do i put down? the ones i bought them with or the ones i put the 2 on.Thanks.
