[quote] Lastly, the baseband processor is usually the master processor, whereas the application processor (which runs the mobile operating system) is the slave. [/quote] Nothing more to say. This article isn't worth the CPU time to render it on my screen. You can hack and exploit the baseband as much as you like, it stays baseband can can do nothing it couldn't do anytime on any location in the network. IOW, don't worry about what's going on in your modem. It's even less interesting than what's going on in your harddisk of your PC. Since the harddisk could actually introduce a infected bootloader or kernel to your system, the modem is sth you rarely ever boot from. ;-P incredible Thanks Dos1! :-) /j -- () 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)
