I just received a press release saying that Onavo (free for a limited time) has just won another award. This app helps you get the most out of your data plan. It works in the background to compress your data usage so that you are effectively doubling or even tripling the amount of data usage available to you. The app is optimized for travelers, when data usage can be most expensive. Note, though, that although they're intending to add this capability, the app doesn't currently compress streaming video or VoIP usage such as Skype.
