I have not found anything in the app store or other stores, Is there any known full device/disk encryption software for android 2.2, that you have test on your device? if so what is the device?

FYI:I know honeycomb supports this natively, but my device does not support HC.

You wouldn't be able to get it via an app, you'd need it at the ROM level. I doubt anyone has done it. – Matthew Read Jul 2 '11 at 13:08

Full device/disk encryption can only be done correct with OS privileges. That's why there is no such App. But newer Android versions and some ROMs provide this features. Have a look at "Are there any known rom(s) with full device encryption incorporated?"

That's why there is no such app. ~> You are saying like there's no root app in the world. Apps can do this with root access. – Evil Angel Aug 18 '12 at 14:36
