Would a wrist mount work for you?
If the phone is small and you just use it as a phone and not as a GPS/wattage+cadence+speed+etc. data logger, you might consider a wrist or arm mount. This isolates the phone from road vibration, you can answer a call without removing it from a mount (or dropping it), buy one mount but use it on multiple bikes, and the phone stays with you when off the bike. I was quite skeptical, but when wearing this on the inside of my left wrist I almost forget the phone is there.
I got mine from http://www.jaminnov.com/index.htm
My flip-style phone has a small antenna so I was able to buy his $5 special
and as he states, the lettering that transferred to the clear plastic rubs off to the point it is not an issue.
