LCD evaluation and other preparations for FC handset

[Das Signal]

Hi Mychaela,

You are unfortunately correct, that trace is on L6. Looking at L7
and bottom layers, there are many traces and I can't see any easy way
that trace could be cut without a PhD in PCB microsurgery. :/

Cool! Thanks for the explanation. For the curious: https://imgur.com/a/3Jife
If you look at http://wiki.openmoko.org/wiki/Who_is_Who apparently Tim Lee
was the hardware manager, Allen may have been Allen Chang (hw engineer),
Shawn was most likely Shawn Lin (RF Engineer), Jean and Shanny I'm not sure.
