....well, not exactly but there is some help (although its digital vs. optical)..
We all know that small sensor P&S cameras, phone cameras etc. cannot really
show a nice bokeh like DSLRs with a fast lens, but here is at least some help.
Main thing - it is a very convenient and fast workaround just using the phone,
without any extensive software post processing.
Recently I made Camera+ (v2.4) my default camera on my iPhone (replacing the iOS camera).
It comes with many neat pre-sets and what I really like is that it allows exposure lock !!
One of the many creative settings is 'miniature' (used above) that gives a pretty decent 'quasi-bokeh'.
Other neat features are: built in image framing, WB lock, 36 quick filters/effects, direct saving to Camera Roll,
self timer mode, easy web sharing (Facebook, Twitter, Flickr), stabilizer, burst mode etc. Basically, it is
a Camera with quick edits built-in. (regular iPhone OS camera has no editing features).
Give it a shot, it is one of the best $1.99 I have spent on iPhone app.
