XM talking with carriers about radio on cellphones: from Endgadget.com

[Victor Healey]

So, XM looks like the latest company looking to cash get in on the
whole music cellphone thang. It seems like maybe they're rethinking
their whole "buy a bunch of expensive proprietary equipment to use our
service" business model in general, as they also recently launched a
desktop radio service with AOL. In any case, they want us all to know
they're in talks with the wireless carriers about making some sort of
satellite radio service available via your cell — no deals are in
place and they don't really have any details to tell us, but they felt
it was important for us all to know. Thanks for keeping us in the
loop, guys.
