Apple now field-testing iOS 5 with App Store applications (update: AT&T, too)

App Store developer FutureTap just revealed that they have received their first crash report from an iOS 5 device. This means that Apple is currently field-testing their next-generation mobile operating system that runs on the iPhone, iPad, and iPod touch with applications from the iOS App Store. The application apparently crashed in iOS 5 due to the MKUserLocationBreadCrumb. Developer Will Strafach (Chronic) let us know that this API relates to the iOS maps and location functionality.

This could possibly mean that Apple changed up some map and location APIs in iOS 5, causing issues with map-based applications built for current versions of iOS 4. iOS 5 is expected to take on some new cloud-based features and will be officially unveiled at Apple’s World Wide Developers Conference in early June. Apple is expected to release iOS 5 in September alongside the fifth-generation iPhone. Thanks, Peter Silie!

Update: FutureTap sent us the below screenshot of their iOS 5 hits. Their WhereTo application has seen five iOS 5.0 and four of the hits come from AT&T HQ. This means that both Apple and their largest carrier are actively testing the new operating system before its early June preview. The AT&T-based device(s) is the iPhone 4 (iPhone 3,1) and the hit from Apple HQ comes from a first-generation iPad. We don’t learn much, but at least we now know that iOS 5 will seemingly not require the dual-core A5 processor in the next iPhone and iPad 2.
