Dear Community:

For GTA02 SD card interference GPS issue, our hardware team provide a 
hardware fix/workaround for this coexistence bug. Sorry post it late, 
because we have to make sure this fix works and don't have side effects.

Here is the fix:

This fix could give almost same performance with SD card out of case.

But this work still not suggest do by yourself, also, this fix need 
proper size capacitor (10 pf with 0402 package), and some solder technique.

We saw people ask about service issues of Openmoko devices, and we are 
working on it. Our sales discussing with our distributor about proper 
services model, but do not have consensus yet, I will keep update it.
