I loved my treo for about 5 days. Then the speaker just went out-- I caould hear nothing without my headset. then a huge buzz developed in the headset. I had to wait 12 days for a replacement which came out of the box doing the exact same thing. After about three hours on the phone with various customer service folks, a THIRD treo was sent to me, and guess what? After two days I have no speaker and a huge buzz. What kind of phone is that?On the pkus side, my email function works great, but I need the phone. I am in the process of waiting for a &quot;senior executive&quot; to call me, but haven't heard a word in 48 hours. I am not a happy camper. Do I dare to try a fourth unit???
