It looks like they have a healthier attitude about sharing this kind of stuff than the Westerners do. So far we've known about 52rd.com hosting "contraband" phone handset chip documents, and now we know there's also baisi.net... But I find it strange that only PDF datasheets and PPT presentations have been found so far, and not, for example, any of the source/object-mix packages that must have been given for the firmware side of things by TI et al to the same folks (phone makers?) to whom they've given the chip docs. NDA etc issues ought to be the same... Or maybe I just haven't been looking hard enough... Would anyone here perchance happen to have a link to some place on one of those Chinese sites that has the original FW source (or semi-source, as in bits of source mixed with binary object blobs) for the Leonardo reference board or for some other Calypso-based HW version that's more readily available (as in HW availability) than the famous TSM30 version? (I realize that it would never be acceptable to use any such code in a Western FOSS project like OsmocomBB, but I would still *love* to take a peek at the original code for some phone whose HW is better understood and/or more readily available than the TSM30.) Hmm. I agree that TWL3025 must be some equivalent Iota variant, and I think you are right about TWL3016 being Syren: the Rita_intro.pdf document in my collection (see my FTP site) says "It is compatible with Iota (TWL3014) and Syren (TWL3016) ABB chips". However, the Iota_intro.pdf document (same FTP site) shows the Nausica->Iota->Syren evolutionary line and lists Syren as EDGE-capable. But Sylvain says TWL3016 doesn't do EDGE either. Hmm. Are you sure? MS
