In January I traded in my Blackberry for a Treo 750 purely for the Activesync feature and the ability to sync the phone without having to connect to a desktop.The pro's to this phone are one: Activesync to Exchange. It works great and has never failed me.The con's are too numerous to mention.The phone has pathetic battery life, admittedly I spend the day on my phone so I carry three batteries to get through a 12 hour day.The touch screen has two locking features to stop you from dialing someone, the first is a numeric lock and the second requires that you push the center button to unlock, somehow the phone still manages to dial numbers when in its holster.Does not switch to the G network when in a g area. This may be an ATT issue but the phone will not switch to the G mode when you re-enter a G coverage area, rebooting the phone brings it back to G but that is the only way to get it on the G Networks.The phone crashes as many as 14 times a day requiring a reboot either soft or hard. This may include not be able to hang up from a call or as has been happening today a crash error message being sent from the phone when it crashes with no explanation. ATT's response to this is, do a hard reboot. That is great done that six times today so far and still having the same issue.I would expect that this may be an individual hardware issue but no, this is the third handset that I have received from ATT. On the first the touch sensitive screen stopped working after a week and the phone would require a hard reboot to get it working.On the second handset the phone would randomly reboot itself, this resolved all the issues I was having including hanging up during calls. ATT's great solution was replace the battery. Did that twice before they replaced the handset.Number 3 is doing a combination of the three, some days it won't hang up from a call unless you do a soft reboot or remove and replace the batteries, other days it won't allow access to the touch screen after a call and other days it reboots itself.The final issue to be aware of is the bluetooth, it works great most of the time, however dont try to dial a call after you hang up from a call. Wait a few seconds as if you dont the phone will drop the bluetooth headset. Recently this has no longer been an issue as I have to remove the battery after every call to hang up which forces a reboot.Treo 750 Sucks. Save your money and either buy a Blackberry or another Smartphone.
