looking for extended battery cover with good GPS antenna

[wallymann]

I picked up a 3500mah batt which gives me killer life, but the included battery cover has a terrible GPS antenna. Instead of 20ft or better accuracy, if i can get a lock get 200-300ft at best...terrible, phone can't work for GPS navigation.

Anyone come across a 3500mah extended battery that has a cover with good GPS performance?
