Will Sprint insurance replace my iPhone?

My iPhone 5 screen cracked the other day. I pay about $24 for insurance for two iPhones (12 each) and I was wondering if they will replace my broken one? They did replace my other iPhone which was acting up before but wasn't broken.

Depends whether your insurance covers accidents such as where you drop it, difference insurance policies cover different things. Read the policy.

Yep. You'll pay the deductible, send your old one in, and they'll send you a refurb.
