Default [Q] I would like to disable my cell radio completely. Help?

I am no longer using the g2x as a cell phone.
I am keeping in service, however, as a PMP. I like the sound quality, and because the DAC on my new phone is vastly inferior and noisy, I kept my g2x for music.

However, I removed the SIM card and now the battery is drained as the phone seems to still be searching for a signal.

Is there any way to mitigate the battery losses or disable cell function altogether without activating airplane mode?
Activating airplane mode effectively kills battery stats and leaves me vulnerable to a dead battery.

Thank You for your help.
