Well, I didn't find anything on my little Ericsson GH337 so I
reverse-engineered it myself.
I haven't gotten the pinout 100% yet, but it's a start.
It's a chip-on-glass type LCD 3-lines, 12 chars pr line.  Char blocks are
buildt up matrix style so fonts and graphics can possibly be defined.  It
also has 2-3 extra fields on the edges for signal-strenght and volume info.
(Theese would be great for a simple MP3 player!)
The display was on the same bus as a I2C type Real Time Clock from Philips
so it's most likely a i2c based interface.  This is cool as it's easy to
talk to with any PIC!

If one number the pinns from chip to edge of glass, 1-6, one gets the
following pinout:
1    SDA
2    VCC or enable?
3    LCD voltage or enable?
4    VCC or enable?
5    GND
6    SCL

Pinns 2 and 4 are connected in the phone I had here.
A resistor is placed between pin 4 and 3, giving me an indication that pin 3
might be LCD voltage, but it may also be a pullup fro the enable line...
Most of theese displays are static in their protocol so it should be
possible to find out something by trying to talk to it.

I don't know if this will be useful to anyone but it's great fun!!!
