Hello, I'm new to this forum. I've just jailbroken my iPhone 4 and im likely to have lots of questions. My first one is about MyWi 4.0, I've downloaded the cracked version and installed it, but before using it is it completely free to use? Or will I get a bill on my contract at the end of the month? Also I'm wondering how it works... If I've got MyWi up and running on my iPhone does that mean it's using WiFi therefore it's faster then my usual 3G connection?
