Yes, every country's iTunes app store is different, with different pricing and a slightly different selection of apps. Until recently the Australian apps were more expensive than the US store $1.19 vs $0.99, though Apple has thankfully revised this.

This is getting confusing though. I have updated BB 2011 to the 319 beta hoping that would fix the Quicktime 7.7 error, however I am still getting that error. If 2011.5 is needed for the new BB app, am I still entitled to use the old BB app wih 2011? The app store doesn't allow for different versions of apps simultaneously. PGMusic would need to have 2 completely separately available apps: the old version for 2011 and the new version for 2011.5. If I allowed my iphone to automatically update my BB app to 1.1 would that mean that I couldn't use it anymore because I don't have 2011.5? Seems unfair to me, especially as the original version of the app was always a bit touchy/problematical and we shouln't have to pay for bugfixes.

(Sorry for rambling, having trouble explaining myself!)
