Mdz: /* Unlocking the modem */

North American ThinkPads have the Sierra Wireless MC8765 card.
European ThinkPads have the Sierra Wireless MC8755 card.

The only difference between the two is the frequency at which they support WCDMA. The MC8765 supports WCDMA800 and WCDMA1900, while the MC8755 supports only WCDMA2100.

Both models support GPRS and EDGE at 850, 900, 1800, and 1900MHz.

Both models are category 11/12 UMTS devices, meaning they support up to 1.8Mbps downstream using QPSK modulation. They do not support 16QAM modulation.

According to the T61 hardware maintenance manual, the T61 uses the MC8775, which is quad band EDGE (850/900/1800/1900) and tri band HSDPA (850/1900/2100).

=== Sierra Wireless MC8765 1199:6805 support ===

The model 2613-ETU T60p (and possibly others) has one of these cards which the linux <tt>sierra</tt> device driver does not automatically recognize (as of kernel 2.6.24.4, at least). While it's the same device in every other respect the PCI id isn't standard, presumably because IBM/Lenovo use their own PCI ids to restrict the use of arbitrary 3rd party cards. Using the 2.6.23+ hotplug infrastructure, we can cause the driver to claim it anyway and register serial devices in <tt>/dev</tt> for it.

To do this using the '''udev''' subsystem, edit or create the file <tt>/etc/udev/rules.d/98-local.rules</tt> file and add:
