I would recommend Acrobits. Not free but only a few bucks. It works fine

This begs the question... which is more expensive (and where)...
making a regular cell call or making a SIP call over 3G ?
Depends on where you're calling and your cellular LD plan.
For example, an "AT&T World Connect" (paying an addition $3/mo) call to
Nigeria on my iPhone would cost me about $0.60USD/min (A non-World
Connect call would be $3.50/min, so lets just go with World Connect).
Patching that same call into my Teliax account via SIP over 3G would be
(worst case) $0.16USD/min, assuming that I didn't go over the 2GB of
dataplan that I pay for whether I use or not.
Now if I don't have a "data plan" and have to pay the the equivalent of
$25/2GB, the numbers go quite the opposite way.
Using Google's calculator = (25 U.S. dollars) per (2 gigabytes) =
0.000149 USD/kilobit (note kilobit here).
A G.711 call is about 80kilobits/sec each way. That comes out to
0.011920USD/sec * 2 (bidirectional). So, round to $0.024USD/sec, times
60 seconds in a minute, comes out to $1.44USD/min data + $0.16USD/min in
termination.
I think.
My math could be off by an order of magnitude somewhere. And your
mileage may vary depending on codec used.
