I thought it was time to involve Apple. Most (if not all) of the 50+ petitioners are iPhone users, after all:

Subject: O2 Network coverage within London
I'm writing to you within Apple as a last resort. Over 50 of us in the same building in Southwark Street in London, SE1, have had difficulties connecting to the O2 3g network since June. And despite numerous complaints, escalations and finally a petition sent to the CEO's office, O2 are unable to give us a date as to when these issues will be reconciled.
We've documented our campaign at http://www.billbuchan.com/o2/
We would like to contact someone within Apple here in the UK who may be able to exert pressure on O2 to improve their 3g network. Currently, within London it is in a poor, and in my opinion, badly managed state. The network outside London - especially here in Scotland where I live - is non-existant.
All of which reflects on your product - the iPhone - which we all have paid for.
The level of customer service we have received from O2 has been shockingly bad. This is difficult to reconcile with Apple's excellent customer support. And its difficult to see why you would sign an exclusive deal with O2 without very strong assurances that they could in fact run network services properly.
