-- FIXED --

By replacing the main screen<>body connecting ribbon, at cost: £6, the phone display is back in action. No soldering damage then!

Now to try and get the microusb back in place safely. Worth scraping the copper rails out, or too risky at this point?

Thanks to all for your optimism and hacker/tinkerer spirit. One happy N900 user still in the game.

To think I was about to prepare to buy a Ubuntu phone. OK, I'm still quite taken by the idea of a convergent phone/PC, but that at least can wait now!

PS: @Kangal - to be clear, I'm not a soldier
