Get $375 out my 3.0 unlocked phone somewhere. Sign up for new line on my plan, with a 16GB phone ($199+18 activation+$26 tax) Have AT&T switch the phone numbers so my phone number is on the new line. ETF the old line ($175-$30 for having been around 6 months) So I get the phone for $388 total instead of $443 ($399+18+26). My contract is reset for 2 more years, I keep my number, and since I'm cancelling the old line at the same time as setting up a new line, I don't have to pay for a month of service I don't need. I'll pay for the first half of the month on the cancelled line, and the second half of the month on the new line. Anyone pulled off something similar? I'm looking for confirmation that this will work 100% before I run off selling my 3G.
