Hi Luca!
that was only a step to be sure that GSM did not remain On for some obscure
reason, to be paranoid I did all my test removing gsm stuff from init
startup, powering off the device and removing/replacing battery :)

Anyway, I did the test you requested:

Qtopia access GSM layer directly and is started by X scripts, that's the
reason I removed it. I'm speaking about qtopia on x11 of 2008.12.

Sorry, I agree with you, but my English is not always clear! I mean We
should update the wiki page as *that page* reports Kingston SD are working
well!

I'm going to buy a new SD card in the meaning too, hoping it will work fine
even at low GSM coverage, it's from setpember 2008 I own a freerunner and
for one or other reason I cannot yet use it as my daily phone!
