T-Mobile Internet - warning!
 

Installing the ZTE T-Mobile Mobile Broadband drivers will leave your Snow Leopard system unbootable! If your thinking of getting mobile broadband, make sure it's NOT T-Mobile!!

Here's some solutions:

• Download the kexts attached and install them.
• Reboot your computer with the T-Mobile ZTE dongle plugged in.
• Open System preferences and click "Network"
• In the sidebar, press ZTEUSBModem.
• For the telephone number, type *99#
• For the account name, type "user" (without quotes)
• For password, type "wap" (without quotes)
• Now click the "Advanced..." tab.
• Use the modem vendor as "Generic" and use the model "GPRS (GSM/3G)"
• For the APN: "general.t-mobile.uk" (without quotes, for the UK. Google your country's T-Mobile APN).
• Leave "CID" set to "1".
• Click "OK" and press connect.
• You should now be connected to T-Mobile!

Method 2: (another computer running Mac OS X Leopard is required.)

• Connect a direct ethernet cable between the Leopard computer (Host) and the Snow Leopard computer (Client).
• Go to system prefs and click "Network" (On the client computer)
• Set "Configure IPv4" to "Manually"
• For the IP address, make it "192.168.2.2"
• On the host machine, plug in your T-Mobile ZTE stick and connect using the T-Mobile app.
• Go to system prefs > Sharing (on host)
• Click "Internet Sharing" in the sidebar.
• Make sure "share your connection from:" is set to "ZTEUSBModem" and in the box, check the checkbox "Ethernet adapter (en0".
• Now, on the client computer, go back to the Network pref pane and click "Ethernet". Now set "Configure IPv4" to "Automatically".

  The host will now assign the client computer an IP address automatically, due to the awesome Internet sharing method within OS X.
  --
  You should now be connected to the internet!!

I currently use method 2, because for some reason, after doing method 1 and restarting Snow Leopard, it does not detect the modem anymore :mad:

Anyway, I hope this has helped some people and given them a warning!
