As you may have heard me say before, the iPhone can do pretty much everything under the sun except open a bottle of champagne thanks to its amazing apps — except use its 3G goodness to make calls from Skype, that is. You could use any open WiFi signal to dial up your pals for free over the Internet, but Apple drew the line at you hopping on its 3G signals to use voice over IP.
After much grumbling from the geek population (including a few gripes from yours truly), Apple has finally allowed 3G voice over Internet calling, which includes using your free Skype App. Hop on your signal to call whomever, whenever, and now you don't have to go searching around town for a free WiFi signal in parts of town you aren't familiar with. If only this would have come up a few weeks ago when I was abroad, it would have made my traveling life so much easier.
