You're not going to be saving $400, only $200. Don't forget, you have to pay the ETF if you cancel your old line. In the end, the phone will cost around $500 when you factor in the $175 ETF.
oh s h i t thats right, i forgot about the ETF. Thank you. Well, i guess it would be cheaper to keep then to keep $9.99 second line for the 12 months. This way if i keep it, then that line will be eligible for the upgrade in 2 years, and my current in one will be eligible next year.
Honestly I have absolutley fried my brain over this whole thing. Is the 3GS THAT much better then my jailbroken 3G? Prolly not, but it doesnt matter cuz..
I GOT TO HAVE IT!!!!!!!!!!!!!!!!!!!!!!!!!!
