Problems with 3G Internet & Unlocking Huawei E220
Recently my 3G mobile internet has begun to fail at an increasing rate. Basically, it doesn't fetch a IP and hangs at "Authenticating". I enabled verbose logging (OS X - System Preferences - Network - Huawei - Advanced - PPP - Settings: Configuration - Verbose logging)
And checked the logs (Application - Utilities - Console - /var/log/ppp.log) and found:

Basically, timed out. Talking to support they didn't see any problems. They thought it was a drivers related problem. But since I couldn't connect on Windows either (via parallels) I thought it might be a hardware problem.
Here's the tricky part: I have a spare Huawei E220, but locked on another provider. Thus I needed to unlock it to even try my hardware problem thesis. Turns out unlocking Huawei E220 was quite easy, a lot easier that up to date cellphones from Nokia or Sony Ericsson.
I won't go into the deails of unlocking here (not sure about the legality about describing the process) but it's pretty clear-cut and can be found on Google.
Turns out I was right, hardware indeed. And now I can connect again.
