This has been a running battle between Apple, the phone companies and those who want to tether their phones to other devices.  Well, here is latest update in the battle, and this time, its a tether that not only does not require jailbreak, but does not even require the installation of an app!  THIS is new..

I have not tested this myself, so I’m taking the video at face value, but the basic here is you tether by launching a new HTML5 web app for the iPhone that lets you tether your 3G-enabled iPhone or iPad to any wireless-enabled device. Right now you can sign up for a free trial if you use blackberry or Android, $15  a year for iphone.

What makes this interesting, assuming this works well, is that Apple cannot remove this app from the app store because this is a webservice.  I’m sure they will try to find a way to block it, or sue Tether.  Regardless, this is clearly not the end of the story; we’ll keep you posted.  Till then, check out the Vid below.
