Unlocking an iPhone for non-O2 SIMs

So I finally joined the 21st century, boosted my Apple nerd cred, and got a funky phone to boot. An iPhone is now in my posession! So far so good, except for one small problem - I have 12 months left on my Orange contract and I don't really want to pay all that off now just to get an O2 contract. I need a way to get the iPhone to work with my Orange SIM.

Enter ... QuickPWN and PWNTools! These two excellent apps allow you to unlock and jailbreak your iPhone in style and comfort. It's not as straightforward as just following the instructions, though, so allow me to elaborate a bit.

Silverlight ... ouch!

For some reason, several places on the web with streaming video (e.g. ITV player) have gone with Microsoft's Silverlight for the interface. I have no idea what Silverlight is like as a platform, but I do know that it's a really bad choice for streaming video.
The main problem I have with it is that, on a 6MB/s ADSL connection, I get skip free performance from the likes of youtube and the BBC iplayer. Silverlight players, not so much. 0% left in the buffer every 30 seconds or so for even small videos, and there is no apparent way to change the buffer settings.
If anyone knows how I can make Silverlight less crappy, please to be posting comments!
