I just noticed that after the latest update garageband works on the iPhone as well.

Bought the app when I got my iPad love playing with it although I cannot play a note.

Now it sounds great on my 4s as well.

OK, embarrassing question time!

I've had garageband on my Macbook & Mac since I got them and haven't been able to work out how to use them I guess you need to have an instrument you can plug into the hardware? Is it the same on the iPad/iPhone, or can you do stuff without?? I love playing about with things like Virtuoso and stuff, but I there's no point shelling out for an app if it needs things I don't have in order to work!!
