I have 2 devices,iphone with 4.3.1 and ipod with 5.0.
The problem is that in my iphone the debugger stop in break points, and in ipod the debugger won't stop on break points.
Any ideas on why that happens?
Have you installed the iOS 5 SDK in your Mac? I think that is what you require.
Also you need to understand that some of the functionalities might still be missing in some of the cases as it is still a BETA version. It might not be a fully functional version yet.
So either you can try using the iOS 5 SDK in your mac or if you have already tried it then I think you should wait for the final iOS 5 full version to work properly.
Also in the below link, they have discussed that some of the functionalities of iOS 5 still doesn't work on iPod. So may be Apple is working on it before the final launch.
