Comment 1 for bug 1067546

The last version of OAuthConsumer is available on this branch:
https://code.launchpad.net/~jose-exposito89/ubuntuone-ios-files/social-networking

Check the TODO in OAuth/Categories/NSMutableURLRequest+Parameter.m if you want to update it.
I don't know if the problems with PUT request with the upstream code is a bug of U1 or OAuthConsumer but this TODO (present in the previous version) solves the problem
