all “modern” baseband processors (MTK, Qualcomm etc) have ROM bootloaders which perform cryptographic verification of downloaded fw images, and will not boot any image that has not been signed by the secret key corresponding to the public key whose hash is burned into OTP (one-time programmable) fuses right in the modem chip silicon! The FSF term for this freedom-robbing feature is tivoization.

The second operating system hiding in every mobile phone

I’ve always known this, and I’m sure most of you do too, but we never really talk about it. Every smartphone or other device with mobile communications capability (e.g. 3G or LTE) actually runs not one, but two operating systems. Aside from the operating system that we as end-users see (Android, iOS, PalmOS), it also runs a small operating system that manages everything related to radio

By GTA0x I meant GTA01 and GTA02. GolDeliCo’ so-called “GTA04” is rather badly misnamed: GTA originally stood for “GSM-TI-AGPS”; thus a device that does not use a GSM chipset from TI cannot be properly called GTA0x.

It is also quite misleading that Nikolaus markets his product as an “upgrade” to the good old Openmoko phones, as it is actually a downgrade: it replaces a free-able GSM modem (i.e., one on which the ability to run 100% free fw is within reach) with a non-freeable one, i.e., one on which such freeing is totally out of reach.
