Ok so i finally got the 3gs...But have problems with wifi and gps. My 3g gets full bars on wifi sitting next to router my 3gs gets one or two. Installed navigon on both. Driving 3g picks up gps no prob. 3gs the program always wants to go into simulation mode and never finds gps, but if i reboot 3gs it will usually finds the gps...Is it just me or anybody else see that there 3g works better with wifi and gps. Maybe i need to see if i can exchange the 3gs. Any thoughts?
