This phone has been a surprise I thought it was going to be a good phone but it's actually a great phone, from the 3G to the wifi to the software that came with it. but one of the things you don't hear about is the fact that this phone can handle two Bluetooth devices in the same time , and to my surprise I downloaded My TomTom navigator five software , that was great because I did not think it would work ,it worked fine in treo 650 , but I didn't think I would be able to download it on to my Cingular 8525 ,but it worked great , and that's how I found out, that I was able to use two Bluetooth devices in the same time , I have a BlueParrott B150TK RoadWarrior Bluetooth Noise-Canceling Headset , the best blue tooth I ever used ,maybe the most ugly Bluetooth I ever used ,I am a truck driver and it's very noisy this is the first one that works great on receiving and sending .but anyway back to the 8525 . I had my navigation system working with my Bluetooth receiver, and I was talking with my headset in the same time, you lose the vocal directions of the GPS when you talk But on your Bluetooth headset and that's it.With excel I could keep up with my hours of work ,and you can download the things you may want that are not on the phone ,like in my case I downloaded (1-Calc - the Revolutionary calculator)This calculator has everything ,From Currency Converter to Unit Converter toScientific Functions and more, so basically this phone does a great job and everything I needed it to do, it does take a little time to get to know your way around, like any new phone you get a different brand, the buttons are configured differently.Now all we need is a phone that could take out the trash. And do the dishes.
