I'm a little fuzzy on this approach so please help me out...
Your strategy:
Pay $500 or $600 for the phone spread out over several months of $50 payments
versus
Alternative strategy:
Pick up a $10/month feature-phone line, which you use to get a new upgrade -> then use the upgrade* to buy the phone for $150 or $160
I suck at math, but even if you lock into the feature-phone line for 2 years, at the end you come up with:
$160 phone (actually it's $150 at Amazon at the moment)
+ $240 cost of extra line ($10 x 24 months)
___________________
= $400 total, rather than the $500 or $600 paid with just one line. Maybe I'm missing something?

PS *Of course I left out the part where you do all the swapping and end up keeping unlimited -- that's what the rest of this thread already discusses, so no point repeating here.
