There are numerous parts of that licence that are incompatible with the GPL and other Free Software/Open Source licences:
This license does not allow You to use the Licensed Application on any iPod touch or iPhone that You do not own or control, and You may not distribute or make the Licensed Application available over a network where it could be used by multiple devices at the same time. You may not rent, lease, lend, sell, redistribute or sublicense the Licensed Application.
If $COMPANY (e.g. Canonical gives me a Linux kernel) gives me a piece of GPL software, I am allowed to install that on numerous devices, I am allowed to sell that software myself and keep all the money myself, I am allowed to install that software on my friend's computer. All of these actions are prohibited by that Apple Licence, and hence in order for Apple to give/sell me a GPL programme they would have to change that.
Apple have chosen to get around this situation by not giving me any GPL licenced software.
