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) signature.asc Description: This is a digitally signed message part. ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

Maybe some sorted testing should be done before publishing "facts".

No, the GTA04A5 will keep the Neo's exterior as it is. It is still a motherboard replacement. But as before you may be able to design your own case around it. > A long time ago, people were interested in replacing the Calypso with > a Telit modem for future devices; as you might think about a new > platform, I wonder if the Telit modems might be considered, still? Initially we tried with the Telit modems but they were not flat enough and we would have had to sacrifice the speaker (handsfree). Fortunately we found the GTM601 which is used in the GTA04A1-A4. > The big difference to the Qualcomms is, that the user documentation is > much better, including a freely available full AT command reference > [2] and more.

The same holds with the Cinterion PxS8 modules. Documentation is also available w/o problems. We are currently evaluating all these options, but there are technical and commercial aspects to consider. E.g. the Telit xE910 modems are 10% thicker and likely still too thick. > An extra wish would be using a main SoC with ARM Mali graphics, so > free GPU drivers would be realistic (in contrast to all other options > it seems). > I'd certainly be in. There is no plan to change the CPU since the OMAP3/DM3730 is still the best mobile processor that can easily be purchased in small quantities. And (despite the GPU) it is very well documented and supported by mainline linux. So please don't expect a wonder to happen... Just small steps and improvements.
