Do you have (or have you used) a quad-band GSM phone? The only ones I have seen are the Motorola v400, Motorola v500, Motorola v600, the NEC 525, the Palm Treo 600, and the Sharp GX32. (It does not look like Nokia or Sony Ericsson have any to offer, even the new SE p910 comes in three different tri-band options instead of a quad-band, how stupid!). While not a Motorola fan, I am leaning towards the v600 for now. But … any suggestions?
