Motorola MOTOKRZR K3 and Smart 3G

Word of Warning: I am a Linux user and very keen in buying a Motorola Razr (specifically v3xx) because it is known to work in Linux. But for some stupid reason I bought a newer model and it is NOT based on this chipset anymore:

# lsusb

Bus 001 Device 002: ID 22b8:6402 Motorola PCS
# dmesg
[30549.844000] cdc_acm 1-1:1.0: ttyACM0: USB ACM device
[30549.844000] usbcore: registered new interface driver cdc_acm
[30549.844000] drivers/usb/class/cdc-acm.c: v0.25:USB Abstract Control
Model driver for USB modems and ISDN adapters
I have not tried yet making it work in Linux but might write a dev driver for this if time permits.

For Smart 3G Internet on the phone, I first sent the following message to 211:
You will receive a browser message. This is a bit noob but only after some fiddling I manage to figure out that I need to see the Options of that message and Install. This message essentially contains the Smart 3G-related browser settings. I previously used a Globe SIM so the default set Web Sesssion is Globe Internet (Menu > Web Access > Web Sessions). Make Smart Internet as the default web session.

To use it as a modem on Windoze, install the Motorola Phone Tools, then Click Internet. It will automagically create a new Connection (with default Smart provider settings that comes with MPT).

Important Note: It takes some time after the 3G registration for the service to be activated.

I got the following actual bandwidth stats using at about 3am in the morning (the other endpoint is a Bayantel server in the Phil):
277kbps downlink (~35 kbytes/second)
109kbps uplink (~14kbytes/second)
Not bad!

At 9pm, uplink 47kbps (~6 kbytes/second), downlink 223 kbps (~28 kbytes/second).

If you have questions, post it as a comment.
