My friend also has the mogul and his has the purple frame around the screen and he also got a refurbished one from sprint after his was totaled and again the purple one.
Anyone confirm this GPS issue? I will stick to purple if it has better gps...But could this also be a software issue? Perhaps the grey/silver phones don't have the latest firmware???
