Telescope attachment for iphone?

I have been trying to find an attachement for my iphone to allow me to take photos through it.
If you have ever tried, you know it is a difficult task to do.

the only one i have found so far is 'Orion SteadyPix' but the reviews are terrible.

Does anyone know where i can find a good one?

Not a clue about quality, but let's be fair, the lens on your Iphone is probably already scratched and marked beyond belief so there isn't much point in considering high end optics.
