Listening to Sirius online used to be restricted to only your PC through their browser-based interface (and a couple 3rd party apps).

That's until someone came along and made SiriuCE. Well, now a new version of the SiriuCE Pocket PC player is available - version 1.11.

With SiriuCE and a Pocket PC phone with flat rate mobile Internet (GPRS is enough, EDGE or CDMA EVDO are OK too but are not necessary) subscribers of Sirius can enjoy it everywhere anytime!
