At last - an easy method to tether any iPhone or Android without jailbreaking or rooting. Saw the news on Mac Rumors this morning and thought I'd give it a whirl.
The method I'm going to cover is for the iPhone and Mac but you can also do it for an Android/PC combination too. This does not require jailbreaking because it uses some groovy stuff in HTML5. First off - get along to Tether.com and register an account - it says that the service costs 30 USD per year but when I got to Paypal to pay, I was pleasantly surprised to see that it only cost 15 USD for the first year.
