I receive the print ads for Micro Center in the mail. On page 18 of the ad for 2/11-3/2 there is an ad for the Nokia N810 for $499. The interesting things is that it specifically states in the N810 ad *Compatible with any GSM Network and *2GB internal flash *Integrated slide keypad, GPS, and micro USB. I looked at the N810 listed on microcenter dot com and it does NOT list the GSM network compatibility or the internal 2GB flash. Does anyone know about the GSM compatibility of the N810? I have an N810 but I am not aware that I can use it on GSM. The product # listed in the ad is 385252.
