i get the message as seen in the title if i try to run my app on the device. i investigated that i have the ios 4.2.1 (8C148) on my device. whats confusing me is the fact that in xcode i only can choose the target(ios deployment target) to be 4.2 and the system-profiler->software->developer shows me "Version: 3.2 (10M2423)"(witch i think is the latest) but under SDKs i only see iPhone OS: 4.2(8C134) and iPhone Simulator: and 4.2(8C134)
could this be the reason for this error, that the device is "newer" than my sdk?
