Sounds like a better option than a full reset. I am still finding things that resetting mine stuffed up

paula, if you iphone isw backed up through itunes, then just click to reset through itunes, then once reset set it up as a new phone and then restore from last back up, sometimes this way round works better than reseting the phone and restoring from backup works better.
a soft reset of holding down the power button and home buttom and keeping holding until the screen goes back and you see the white apple logo normally closes everything out and puts the phone back to normal.
aslong as you keep your phone backed up then really you shouldn't lose anything.
I have a mac and mobileme, so everything syncs apart from music and apps, so I still plug it into the mac every week for a sync and backup.
