How is this different from Privacy Blocker?
1) Permissions is free.
2) Permissions is open source.
3) Permissions does not break market updates for apps that you deny permissions to.
4) Permissions has no reported FC yet?
5)Did I mention Permissions is free?
So, basically, Permissions allows you to effectively control the permissions that apps which are installed onto your phone, via the market or some other source.
This is fully open sourced at

You must reboot before these changes take place and be aware that denying an app a permission that it is requesting may result in the app Force Closing.
Please use the backup feature with care. Always make backups of your device!
