Dear Ian,
> Has anyone done any side channel analysis on phones?
On the constructive side you might want to check out NaCl for ARM (best
with NEON), e.g.
which avoids all software side channel attacks. Not sure how you would
avoid cache attacks in Java.

Cryptographic Research has a demo attacking cell phones running slow
crypto (Java) by electromagnetic radiatiion, see

Attacking fast (good) implementations is a lot harder but wee're looking 
into it. 

All the best
