iPhone, iPad and Blackberry emulator for Windows
I noticed that when my ipod touch is connected to my desktop, iTunes backs up the programs. Can these programs be run on a PC or on a Mac?
They certainly won't run on a PC - it's a completely different processor architecture and operating system.
I don't know enough about Macs to say for certain about them, but I don't think they'll run on Macs either. The operating system is different & the processor is too. In fact modern Macs run on virtually the same CPU as PCs.
