OK, so I'm new to the forum and don't know exactly how it works but here goes... I bought a Droid Eris this past weekend mostly for the iheart radio app. I listen to several stations from XM radio and wanted to get rid of the XM and just use the phone. The trouble is that I can't get the i heart radio to play all the time. I am a truck driver and although my signal is good the station says "buffering" a lot of the time. Any suggestions?? Anyone tried a signal booster, are they worth the money??
