great device. expensive, but really good quality components. doesn't have UTMS (3g) but does have GPS and GSM.
nearly everything is supported on the kernel side that makes this device a useable PDA. enough research has been done to access all the major hardware, with the remainder being a fairly easy tidy-up job, or hardware shared with other devices.
the only major bits of work are now primarily user-space related: the GPS (which is a known proprietary chipset, with people 'on the case') and the GSM. the protocol to communicate with the GSM is known: it could in fact be pretty easily done as a tty line-discipline module (if i knew how to write tty line discipline drivers, i'd do it...)
kernel modules - todo
- Battery monitor (needs asic3_owm common code with universal and hx4700, based on ds1wm)
- Suspend/Resume (look at h4000, take the jump address from universal)
- Charging (gpio trace and IRQ needed)
- camera (same as magician and universal)

3rd container - lots of weird stuff
i thought you might appreciate this: some other people, on a chinese forum, are also doing disassembly of erikson phones, and finding the same chips as listed here :) http://www.ilephone.com/thread-135-1-2.html
unknown: DB2011 751979AZ 59A9FEW SA RIA GI (apparently same chip used in sony/eriksson k500/k700)
unknown: 3040L0YTQ0 A6077631 Z609I228B - 0s could be Os in the first two numbers. vague preliminary searches indicate that this might be an intel flash memory chip.
unknown: DB2202 751543Z 64A20KW $4 RIA GI
unknown: AB2001 R1A TWL93004CZ R61E73KT - on some random russian site apparently this looks like it's a power supply IC.
references to AB2001 R1A here: http://www.gsmhosting.com/vbb/archive/index.php/t-290096.html someone talking about flashing an EROM (whatever that is)... again: it's something associated with an eriksson k700i.
bluetooth: B6150E1 63DVKDT
5th container - probably GSM/GPRS
unknown: RF9388 0614 D013NLB - possibly a power amplifier.
unknown: RF 2010 P1P8M cPG605 P38/1
unknown: 6012 58
unknown: 1RA4B 2020L05 - very difficult to read. chip is 5mm square, 20-pin round edges.
6th container - GPS!
Baseband processor: RL - 20000 E1 0520 Z14 http://www.globallocate.com/SEMICONDUCTORS/SEMI_GL20000_Frameset.htm
LNA and mixer: LN22 P1 6Y 60527 - could be a G0527 http://www.globallocate.com/SEMICONDUCTORS/SEMI_LN22_Frameset.htm
both the LN22 and the RL-20000 have a picture of a globe on them. the LN22 is tiny (4mm x 7mm) with edge-pins and the RL-20000 is a BGA 8x8mm
this area has a crystal in it: R4009 Y63B 4T

2408 WP - some random information:
ASIC 3 - one rev up from the other ipaqs and HTC smartphones (the same as on HTC Universal).
can't edit the HTC_Partnumbers page to add this one. full chipset number is obscured by a cage shield that is soldered to the circuit board. which i just cut away :)

resetting your hw6915 into bootloader
action button* action button + reset (all at the same time for a few seconds)
reset can only be pressed with a stylus. action buttons are the ones in between the phone buttons and the funny joystick selector thingy.
