It appears Apple is testing iOS 5. Developer FutureTap has received a crash report from a device running the next version of Apple's mobile operating system, as confirmed via Twitter.
The crash was apparently caused by something called MKUserLocationBreadCrumb, the API of which, 9to5Mac pointed out, is related to iOS maps and location features. This means that Apple likely made some changes to map-based apps in iOS 5 that are causing problems for older versions of iOS.
Rumors have indicated that iOS could have a focus on cloud-based applications and support, which would include a "locker" for storing music, video, and photos. It could also debut a person-finding feature for tracking friends and family. On top of that, Apple said yesterday it was leveraging location data to create a traffic database for future applications, and the crash could be related to that.
Apple is expected to preview iOS 5 at its annual Worldwide Developers Conference (WWDC) that kicks off on June 5. It's likely that the OS won't be released to the public until this fall.
But what does this mean for the iPhone 5? Apple typically previews an upgrade to iOS in the spring in anticipation of unveiling a new iPhone in the summer. But if the rumors are any indication, Apple might not be launching a new iPhone this summer. There isn't a consensus among Apple rumor mongers as to when the world will see the iPhone 5. For every report that says the smartphone won't appear until this fall, there is one to counter it reporting that Apple will stick to the typical annual update cycle and unveil the device at WWDC this June.
At this point, the launch date projections are just rumors. Apple hasn't commented on the next version of iOS or the next-generation iPhone 5, and probably won't until they're both ready.
