Did you, like us, think charging for tethering was absurd? It would seem O2 doesn’t want to be absurd anymore and is listening to the cries of the people. The image above shows the data options on O2, all of which include free tethering. This means you can use up your 3G connection – no unlimited option yet sadly – as you please, on your laptop, iPad or your desktop if burning data is your thing. Yes, please.
