The first thing is that 99.999% of the contracts said that you are getting "mobile web" or "mobile internet" --- even if your phone has a full browser. "Mobile Internet" is defined as WAP and tethering ain't WAP.
Please people. You get FREE DATA on ALL plans, and your moaning about them charging a little extra for tethering?
No, this is definitely not shocking.
What other countries can say this about the iPhone? You don't realise it yet, but O2 is the single best carrier for an iPhone plan.
Tethering is not widely used, therefore it's not a necessity, it's a luxury.
If you want it, expect to pay through your nose for it. End of.

Since when have O2 only offered 'mobile web' on iphones? The point of iphones is to be able to browse the full internet. I've never seen anyone use a WAP site on an iphone!!
