#3Confirmed on a Google Nexus.
In his webpage he also says "They downgrade all images and insert a javascript link into the HTML of each page."
The image downgrading has been know about for ages, the JS I have not heard about before. I have asked for more info on Twitter but will investigate myself if I can find time today.

https://twitter.com/#!/O2/status/161872584634408960 says "@lewispeckover Hi Lewis. The mobile number in the HTML is linked to how the site determines that your browsing from a mobile device #O2Guru"
As Lewis replies, "@O2 User-agent header ID's the device. Passing mobile number to third party sites is not ok! Seems like a data protection act breach to me?"
Being charitable, that could be clueless support rather than official policy response but hopefully the storm coming their way will get an official response soon.

#7Just tested on o2 Germany, and no such header was inserted. It would probably be illegal here anyway.

While waiting for an upload, I had a look.
This tag is inserted in the head:
http://1.2.3.4/bmi-int-js/bmi.js language="javascript">
This is inserted at the end:
The external JS is here: http://pastebin.com/rv3k4meX
Analysis please. At an initial glance it seems to just be about the image compression.

The javascript changes all image URL's to lower quality versions from O2's servers, it also provides a helpful little function which lets you use a hotkey (Alt+D I believe) to download all the images in full quality. The javascript comes from the domain //1.2.3.4/bmi-int-js/bmi.js (Not a real domain, only works behind O2's proxy)
