Hi all, I checked the first couple pages of the forum and didn't find anything, so here it goes. I'm planning to take advantage T-Mobile's offer to pay my ETF (early termination fee) to switch from AT&T. I have 2 iPhone 6+ scheduled to arrive tomorrow on launch day, and I was wondering how long would it take for AT&T to send the unlock code to me so that I can use it on T-Mobile? Can I pay off the ETF right away at the AT&T store? Or do I have to wait for 2 weeks for AT&T to deliver the unlock code to me while getting stuck on my old old Nokia... Thanks!
