I want to know the answer to the following question:
Which Apple device has the ability to sync with iTunes via the phone network?
All the background I'm provided with is that "This service allows users to access the Music Store from either an iPhone or an iPod Touch and download songs directly to the device that can be synced to the user's iTunes Library over a WiFi connection, or, in the case of an iPhone, the telephone network.". Is that enough to answer the question?
Answer: yes
