Is the iPhone Simulator UDID unique for each installed instance?

Question

i.e. does this call:

NSString *udid = [UIDevice currentDevice].uniqueIdentifier;

return always the same UDID when it is executed on the iPhone

Answer 1

My UDID is reporting as 03B41D62-FB69-5B6D-A95E-473842F4DFE3 from the iPhone Simulator, so it looks like you're correct.
