My game uses the accelerometer so I can't do it in the sim...

I use iSimulate; there are also free alternatives, but I've never used any of them...

thanks for the reply sealfin, I noticed iSimulate has a free lite version, anything wrong with that?

Well, as iSimulate Lite's App Store page states that that version doesn't support the accelerometer it isn't likely to be too useful to you

oops I missed that. Thanks!
