The 3G and 3GS use the same case. I've had my white 3G since the day it came out. I run GPS on 3G all the time. With either Google Maps or XGPS. I run them solely as GPS and though my phone gets a little warm, it's not hot and it surely doesn't disfigure. The only reason my phone isn't a perfect bright white is cause it's a year old now and it's gotten dirty cause I run it caseless. So Dsr1205, you're making a mistake for not wanting to get a white phone. It looks amazing.
