Hello, I live in the UK and I have a phone on the o2 mobile network. Recently I discovered (by accident, I wasnt tying to be clever) how to make free calls between and two o2 mobile phones.

I was wondering what the best way to try and bribe o2 would be, bearing in mind that if they found out my address they could probably then trace my phone to find out what i'd been doing.

I want to say to them something like 'Hey, I can make free calls, if you give me X amount on money I'll tell you how and then you can fix it, otherwise I'll just post it on the internet which will cost you alot more when other people start doing it.'

Any thoughts?
