I have a 2nd gen iPhone 3G and my router is transmitting and receiving at 15 Mbps and my sirius xm program occasionally buffers. Sometimes it doesnt even come back to music and I have to eventually shut it down and reopen the program. Also every now and then it will switch from 128 bits down to 64 bit. You would think that a connection as fast as 15 Mbps would pretty much do away with buffering several times in a half hour period. I sure hope an upgrade version is coming out soon. Is anyone else experiencing problems with this sirius xm program or is it just me?
