I think this is all part of Apple's future Mobile Me strategy.
I just read an interesting story discussing apple's search for RF engineers.

the article links to a Mobile Mag story which speculates the 'Mobile Me' trademark news relating to apple incorporating EDGE technology into the iPod:

Apple definitely has a vision about the future of mobile devices and entertainment, which they beginning to execute. It's interesting to see where this goes, but could Apple be taking staking a claim in the wireless universe and taking on the Wireless Carriers?
In the next few years we will all be enjoying mobile internet access with EDGE/WiMax and many other flavors which will enable some pretty exciting possibilities on handheld devices whether it be ipods/cell phones/treos or the next big thing Apple can dream up.
This is all very cool stuff!
