Just FYI, any app you get credit for has accessed your UDID. If you don't want companies to have access to it, then you shouldn't be using this service. If they don't require account creation, then they just access your UDID and upload it when you run the app. However, afaik, giving your UDID out is really only problematic when it can be tied to other identifiers like email and other accounts, so it probably is safer to skip apps that want you to register an account.
