Hello. I'm hoping someone can give me some insight into pre ordering two iPhone 6 from T-Mobile and porting my numbers so T-Mobile will pay the ETF on both my lines with Verizon. Basically, I want to pro order two iPhone 6 (1 for each line) and port the numbers to T-mobile. Will I be able to preorder the iPhone this Friday the 12th and still have a working Verizon number until the new iPhone arrives on the 19th? I know I'll have to get my final bill from Verizon and send it to T-Mobile to get reimbursed for the ETF. I also know I need to trade in my current iPhones and buy new ones from T-Mobile. I'm going to finance them along with my monthly bill, so that's not my concern. It still comes out less expensive than Verizon. I just want to know how the number porting works on a preorder. Thanks for any insight you guys have!
