Can anyone please provide any pointers on how to resolve this issues. How can I resolve the unsupported file format which is not the architecture being linked (armv6) for architecture armv6 errors. Any help would be greatly appreciated. Thank you!!!

Remove the libraries mentioned and re-add them using the '+' button in 'Link Binary with Libraries' section of your target's Build Phases tab.

I was able to resolve a similar problem but check/adding entries to Search Path segment of the Build Settings for the app.

The Framework Search Paths item contains old references to 4.3 SDK paths that were probably correct before I upgrade to SDK 5.0.

Whether necessary or not, I added entries under Debug for IOS Simulator 5.0 and Any IOS SDK that distinguished between the path through iPhoneSimulator.Platform and iPhoneOS.Platform directories.
