HI, I'm spending Christmas with the in-laws in Austria. That means that I don't have an internet connection through my carrier. They don't have wifi. My iPhone is kinda useless until I go home.

Here is the app that I'm looking for but can't find: I want to connect my phone to the computer via the USB cable. The computer has landline internet (RJ45). Is it possible to connect my phone to the internet if it's connected to a computer that's connected to the internet?

Of course I realise that this isn't optimal, but I don't want to buy a router. I'd like to just turn on MyWi on my old 3G and be able to do whatever I want from mine or my wife's iPhone 4.

Thanks for the suggestions!
