How do I erase the airplane mode from a Motorola iDEN phone?

Even when I’m pretty sure it’s embedded within the phone’s OS, I would like to know if it is technically possible (maybe ‘re-writing’ or ‘re-flashing’ the devices) to erase the airplane mode from, at least, 2 Motorola iDEN phone models: i680 and i415.

If it is possible, how do I do that?

Thanks a lot for your comments.

Why would you want to?

I’m working on a development with a couple of old iDEN phone boards. The user is going to have limited access to the phone’s screen.

OK. Makes sense to me. Sort of…
