Will apple service iphones with installer.app even though we're still with AT&T? Got a phone, unresponsive, won't charge, totally dead. Tried to restore, no go. It's just totally blank, tried system reset, nothing, totally unresponsive. We wanted to exchange it, will apple service it? We're with AT&T, but it has installer.app on there. the iphone will NOT turn on, it's totally dead.
