Just a reworking of Opera Turbo?
Back in 2009 Opera introduced 'Opera Turbo', a HTTP proxy service of sorts where compressed web pages (with much compressed images) were delivered through Opera's servers (in Norway?). I used a Nokia E65 at the time and it really did speed up browsing.
Enabling the Turbo feature essentially routed all HTTP traffic through their servers and you could bypass all sort of blocking on ISP level - downloading Linux Distros via TPB was once again feasible. :-)
