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...)
wlan: TI ACX100 includes
TNETW 1100B ZHH (TNETW1100BZHH C E 65AC9CT),
MAXIM MAX2820 (MAXIM MAX2820 ETM615 NN7N1LQ) and
i2c eeprom: 2408 WP (near the TNETW and MAX2820)
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: 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.
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 :)
