Is anybody even aware of any mainstream mobile email readers that support encryption?
One of my friends uses K9 on his Samsung mobile phone; it works fine for him, allowing him to exchange GPG-encrypted emails with me.
If you need more examples, I could ask on the (encrypted, Schleuder-based) internal mailing list of Digital Society Switzerland.
An encrypted mailing list won't help you much regardless of the compromised nature of your device if you can't even read the encrypted messages. ;)
Personally I prefer to use my mobile phone for plain old telephony and SMS only; I lovingly refer to it as "my dumbphone". I believe that the risk of compromise is much, much lower than for Internet-connected smartphones, even without taking any special security precautions in relation to the dumbphone.
By contrast, a laptop running Debian GNU/Linux can be kept secure enough for my needs without too much trouble even while communicating via the Internet with somewhat-trusted as well as with totally untrusted third parties.
That is good enough for me, because I don't have a need to be online continually while awake; it suffices for me to be able to ensure that I'll be able to live up to a commitment of having promised 24hrs turn-around reaction time for anything that may be relatively urgent. A laptop computer is sufficiently mobile for ensuring that, as long as I don't travel to really remote areas.
