 \\ By the way, since I mentioned the TI Locosto baseband: Maybe someone wants to reverse-engineer the [[http://​bb.osmocom.org/​trac/​wiki/​CalypsoRomloader#​secure-RomloaderonCalypsoplus|serial rom-bootloader]] of this ARM7-based processor, so we can drive the display directly from the phone :-P \\ By the way, since I mentioned the TI Locosto baseband: Maybe someone wants to reverse-engineer the [[http://​bb.osmocom.org/​trac/​wiki/​CalypsoRomloader#​secure-RomloaderonCalypsoplus|serial rom-bootloader]] of this ARM7-based processor, so we can drive the display directly from the phone :-P

-Normally, the baseband board and the display/​keypad pcb are connected with a 32-pin connector (exact model unknown). Luckily there are pull-up resistors and capacitors for every needed signal, so I decided to solder some wires there, instead of directly to the connector. The schematics of this phone are floating around the web (just search for **f3_schem.rar**).+Normally, the baseband board and the display/​keypad pcb are connected with a 32-pin connector (exact model unknown).
