Re: Just newer iPhones??
If she gets a carrier update from Sprint and the problems go away, then maybe it is more widespread. If you check the rev number of the carrier 'blob' before/after an iOS update you can see if the carrier had an update that tagged along. They're responsible for testing iOS updates on their network and issuing updates to the carrier settings if required, looks like Sprint screwed up.
