Temptation is a mofo!

Interesting! It seems that tethering is currently possible on the iPhone.

Now the questions are:

1. Can O2 figure out I'm tethering?
2. Will my account get flagged and whacked with a £15 charge for using tethering?
3. What happens if I go over 3Gb download? Will I then get flagged and charged the higher end tethering charge?
