Please help, I don't want to go back to my old Treo - I'm having a very weird issue when on speaker phone - it cuts off the call but the speaker stays on and will not turn off even when end call is pushed or speaker button is pushed - what is very strange is that the mic all of a sudden gets extremely sensitive and picks up my hand contacting with the back or the buttons and emitts the taps and clicks through the speaker. It will finally turn off after 20 secs or more - but the phone is frozen until then. - please advise
