I emailed the seller who said ignore the box, the phone's been "flashed" and it has 850.
My questions:
1. Is it possible to "flash" an additional frequency into a phone? I've never heard of upgrading a phone this way before but then there's a lot I've never heard of.
2. Is there a way to verify the phone works on 850? I don't THINK I have any 850 carriers around here (North Carolina) but can't find coverage maps that separate out 850 from 1900.
Thanks to all you techies.

1) Answer: Yes, it is possible on Motorola phones that have the GSM 850 disabled. The major factor here is the flash/flex version on the phone. You can flash your own Motorola phone if you have a USB cable with a USB --> miniUSB (the ones used on digital cameras for example) connecter. You have to use a flashing tool such as Motorola's PST, multiflashflex or RSD Lite.
Look for more info on Motomodders.net:

However, Phonescoop.com lists the L6 as being triband only.
2) The only way to see if the Moto is connecting to 850 is to have the Field Engineering Menu activated. You have to seem edit this feature meaning you have to change certain values in the number tables on the phone.
