Slipstream, in a double header news release, announced not only that it's powering a Download Accelerator for Opera's next major release, but has also signed up to join the Symbian Platinum Partner to promote its data compression and acceleration technology to the Symbian OS Platform. Opera already have a nice market for their proxy based acceleration service, and we'd expect v7.6 of the browser to build on this with Slipstreams help.
