Does your cell well yet? You use the bike for Through field?
It's not clear on the pictures posted on google+ link, but under the black tape there's a bit of foam as to avoid any possible issue with vibrations or shocks.
I have to point that my bike hasn't any suspension and I'm often on paths and tracks. No damages on former phone (the one one pictures) and the current one. I did more than 1.000 miles. Never falls off (even when I did). As the phone is really well attached (no move possible, no slide...) no damage can be caused by bumping and bumping on the bike. I also think that as there's no moving part in the phone, vibrations or else should not be feared. For example games based on accelerometer are always fine.
But this is for my own design, I don't know what you have in mind... I hope this helps.
The only point I need to find an improvement could be on a hand-free kit in case of incoming phone call.
And if you search for a great copilot, just give a look to oruxmaps!
