Apart from the "public key" problem, there is another advantage I can think of for using new change addresses, which is privacy.

Cool, thanks!
So then, if I want the extra privacy that I already get with Qt Wallet on my laptop, maybe it's a good idea for me to use a different iPhone wallet besides bitWallet, so one that also uses change addresses? Any recommendations?
Thanks again!

I am not sure exactly about iPhone, but I always liked the fact that blockchain had multiple clients and your wallet was accessible from any device in case you ever lost/broke/stolen this one. Although this does step away from keeping the wallet all to yourself. Blockchain's wallet is quite secure.
