If you've heard anything on this subject please let me know. My P800 isn't out of date yet but I'd like to future-proof it without relying on SE.

Is it possible to get into a situation where flashing can't fix the phone? - it not I'm gonna buy Fighter or DiV and start messing with it.

Absolutely anything at all.

Have you even heard this being discussed or mentioned in a forum somewhere.

Have you looked inside your P800?

The P900 has a set of test points near the memory card slot
that looks like 2 rows of 10. Hmm, I thought, this might be
JTAG.

I have got as far as measuring voltages on these pads and
they seem to agree with what you would see on JTAG.
The next step is to solder a connector onto the board
and make up an adapter cable to a standard ARM 20-way
header.

Then it should be just a matter of using your favourite JTAG
debugger - that handles ARM9 - you can then dump the entire ROM, fiddle with it, and put it back into flash.

The only other complication is: there might be another test
pad somewhere for JTAGEN which will have to be wired high
on startup to enable JTAG.

Why ont just use some sort of unlocking cable such as the Termninator(~£15) for the moment?

What exactly do you mean by JTAG - some sort of programmable eeprom that the phone stores it's OS on?

Don't know what you're talking about but it sounds interesting!
