Australia - Is there a difference re: App that will work?

[sookie]

I'm curious (and new so please don't be upset) but do some apps only work in certain countries?

A prime example is Siri who only does location/maps in the US.

I have a few cydia apps that will not launch but want to confirm if it's my hardware, my downloading or my country.

Any assistance appreciated

Cheers

P.S I'm referring to the above re: cydia on my iphone3 ios5.0.1 (not my 4S 5.1 - not happy )

Yes. Some apps will only work in certain countries. For instance the Pirelli motorcycle speed and route tracking app only works in Europe although I have it installed on my phone.
