do you have recent GSM-modem-firmware? See http://wiki.openmoko.org/wiki/GSM/Flashing Also see the notorious #1024 bug that may only get fixed in HW but should have proper workaround in every existing OS for Freerunner. Other than that, I don't see any vector how poor reception (the only relevant common denominator parameter of the situations where you encounter those problems) could have *any* impact on the long list of problems you listed. For sure device shall not freeze or encounter IO-errors, no matter what's happening to modem. Ooh, wait! In poor-signal conditions the modem also needs to use high TX power. This *could* theoreticaly have impact on whole system when the battery is very old and worn and thus has high ESR thus creating "brownouts" for whole system when modem drives its surges of power consumption to the battery. So maybe swapping battery for a fresh cell (Nokia one, for test purposes. See http://wiki.openmoko.org/wiki/Battery_Questions_and_Answers#Do_other_BL-5.2F6C_compatible_batteries_fit.3F ) might be worth a try. good luck jOERG -- () ascii ribbon campaign - against html e-mail /\ www.asciiribbon.org - against proprietary attachments (alas the above page got scrapped due to resignation(!!), so here some supplementary links:) http://www.georgedillon.com/web/html_email_is_evil.shtml http://www.nonhtmlmail.org/campaign.html http://www.georgedillon.com/web/html_email_is_evil_still.shtml http://www.gerstbach.at/2004/ascii/ (German)
