I am having the same issue. Have you found a solution? – Larry Hipp Oct 29 '10 at 20:53
I found the solution, the P12 file should combine the key file.If the P12 file only contain the personal information, it maybe 2-3KB, if include the key, it should be almost 6KB file. The key is generate from my boss, It may be done via the apple developer program page. – Cheung Tat Ming Oct 31 '10 at 16:55
