You sir are in Luck!
the poster above me has accidently given you false information,
there is a way that will not void the warranty ...
when you set up your iphone on itunes
put in 999-99-9999 when it asks for your s.s. number
then you will be directed to a new page that asks you if you would like to do pay-as-you-go plan
check the pay as you go plan
you must pay the first month, like 50 dollars
after that stop payments
Bingo you have an iphone with everything exept Edge/Voiceplan
it works great
