Why do location dependent systems such as loopt have agreements with network carriers? Is it to support location or to pre-install the apps before sold?
The iPhone OS doesn't allow background processes for third-party apps. So normally Loopt would have no way to update your location except when you open their app. The carrier deal lets them get location data straight from the carrier, whether their app is open or not:<p><a href="http://www.theiphoneblog.com/2009/09/04/loopt-att-work-399month-location-updates-deal-iphone/" rel="nofollow">http://www.theiphoneblog.com/2009/09/04/loopt-att-work-399mo...</a>
