Keep a look out for an official announcement of Sprint getting iPhones later this year. Q3 just started so if there's not an announcement in the next couple weeks it unlikely that anything will be said til July 1st (Q4).

The "rumor" is that Verizon will have one beginning in September/October with Sprint following suit in November/December.

Its also rumored that the Sprint insurance coverage will cover the screen (though I find that highly unlikely).
