try iphone software update…worth a shot theres a 3.0.1 out or some shit… i got it last week or so. if nothing seems to work but thats the only app thats messed up…first try updating the app itself if that dont work start pandora, hit the top power button until you get the power off slide indicator, then hit both buttons top and on the face and hold them down together for like ten seconds and it will exit the program and kick you back to your main screen(like a force quit or task manager end task.). after that restart the app… if it still dont work power cycle the phone wait a few seconds after its actually off and power it back on and try using the ap one more time, after that i would try another ap that does the same thing… if it works use that app… or restore your phone to its origonal settings and start over… if you have LOTS of apps somtimes the phone needs to be restored… apple dude told me that at the store… i had like fucking over a hundred apps… and sometimes after you install an app it makes another one not work… its rare but it has been known to happen.
