Moving from Verizon to AT&T ETF Questions

I’m going to give my girlfriend my old iPhone 3GS and getting rid of her Droid and moving her to the add-a-line on my AT&T Plan to save money.

The question I have is, is the ETF something is is just billed for, and how does moving her number over to AT&T work?

Why do you hate your girlfriend so much?

Her Droid is misbehaving :)

Yeah but AT&T?

Also as far as I know they make you pay the ETF before they will let your number go.

Ok, thanks.

I’m on AT&T with my iPhone, so it makes more sense for her to move to AT&T. I need to be able to use Data and Phone at the same time, so me moving to Verizon isn’t going to work.
