Update: the hair dryer worked! thanks so much maebee!!! ha ha sprint!!!!!!! (not you, sprint employee answerer-- you were helpful.) now back to "pregnancy and parenting" answers...
Update 2: edit #2: well, it worked for 2 hours. it's not working again. i've put it back in front of the hair dryer...
