I figured out a way to use Sirius on the iphone but windows is necessary . What I did was set up a orb account and use usirius which gives you the MMS feeds, which you then take and input into an internet radio stream on the orb control panel. Works well over edge, only downfall is you cannot recieve calls while streaming. Basically you goto mycast.orb.com and then login and do a speedtest so it compresses properly, you then select your streams that you added with the proper mms feed. If anyone knows another way to access mms feeds please let me know.
