Q:Sony-Ericsson data/power connector pin functions

Has anyone discovered the functions of the pins on the 11-pin data/power
connector of the T610 (and similar phones) ?

So far, I figured out (starting count at the outmost pin of the block with 8
pins)

1: ?
2: RTS (?)
3: ?
4: RX
5: TX
6: ?
7: ? - but follows phone power status - I think it's an input with a quite
weak pull-up
8: ?
9: ?
10: GND
11: power (charger input - is always powered) - around 3.6V

Levels are _not_ RS232, but more like 3.3V logic. (hi level around 2.8V)

BTW: mating connectors are available at www.ucables.com, in case anyone
wondered...

I asked S-E developer support about this, but they basically only want to
discuss this for devices that generate substantial extra sales volume. So
much for support....

Anyone?
