Have an iPhone? Have data limits? Or are you traveling to Argentina and need to use your home data plan while here? All these things can be incredibly expensive, but there is a cool new app for the iPhone called Onavo that can save you a lot of data usage and extra charges.
Onavo is free and after you install it on your iPhone, it immediately goes to work in the background compressing all the data coming into and out of your iPhone. I’ve been using it for a few days now and have seen no noticeably slowdown in speed, but have seen a significant decrease in data usage. Pretty cool and definitely one of the apps you should be running.
