I have nokia 6600 60 series. My desk top on the phone tells me i have an alarm set, but when i go to the clock function and try to clear alarm, i find there are no actual alarms set?? plz help

I also have a problem that i cannot delete a file i sent to my phone via infra red. It is a sis file for an app i unistalled. It gives error : "general, already in use"

Am new to 6600 so any help from you guys is v much appreciated. Nokia have told me to send in the phone for repair but there must be something i can do?
