i have a sgp 3.6 and it seems to take forever to get a gps lock if it locks at all. even outside! i have been able to get it lock by putting it on top of my microwave as funny as that sounds. i put it up there and 5 minutes later it is locked. other than that it just wont lock on to a gps signal. i have 2 sgp 5's and 2 4's all of which lock on within seconds inside or outside. it seems to me that the 3.6 has an inferior gps antenna (that isn't the only thing inferior on it) compared to the 4 and 5. anyone else have the 3.6 and noticed this as well? any ideas, suggestions? thanks
