I have been trying to install provisioning profile on my newly bought iPod touch for testing the application that I wrote after 3 months of hard work. This is getting really frustrating for me when I try to push provisioning profile downloaded from program portal it should appear in the "Organiser". However it returns me with an error "The Developer Disk Image could not be mounted. Xcode could not find an appropriate Developer Disk Image to mount on MetaSys iPod. Please contact Apple for the 2.2.1 (5H11a) device support package." If I click on provisioning profiles under it the message in yellow prompts me "A signing identity matching this profile could not be found in your keychain". I have tried many things to work around this with the inputs from apple support pages and internet searches but to no avail. Now I am thinking of formatting to rebuild the OS. Can anyone please help me in resolving this? I am a bit skeptical if I format OS and rebuild it should not cause any new trouble for me. Any ideas?! Thank you in advance.
