this.
Put it on your SD card.
Power off your phone. hold the "X" key on the keyboard and power it on, keep holding on to "X" until it goes into recovery.
(If your using Bugless Beast v0.4 all you need to do press "X" and the power button at the same time.)
Use the volume buttons (Up/down) to navigate to "install zip from sdcard" select it with the camera button.
select "choose zip from sdcard"
Navigate to where you saved the baseband zip. and select it.
It will run and when complete hit the lock/power button to back out to the main menu then select "reboot system now"
That's how you install any zip w/o using ClockworkMod app. Now if you want you don't need that app anymore. I haven't had it installed since the first time I did just to switch to ClockworkMod recovery.
