Query: Very upset ...

I was very upset when I got this phone, specifically upon finding out through Motorola (since as far as I could find, it doesn't say this ANYWHERE in the literature) that the phone receives on the 5.8 GHz frequency, but sends on the 2.4 GHz frequency! That means, for all you wireless network users, that this phone will most likely play havoc with your signal until you play with your network to fix it. You CANNOT modulate the phone's signal to fix it. It's a real bummer.Everyone should know this before buying it -- it's a pity Motorola chooses to hide this fact, because for someone like me, I had to choose between my wireless network or the phone. I chose the wireless network!Hope you have more luck than me!
