iPhone kiosk

[Richard Miller]

Hoping someone here knows the answer to this. I realize it's an unusual 
situation.

I am setting up a jail-broken iPhone with a LC app. This phone will be 
set to boot directly into the LC app. The phone will only ever be used 
for this one purpose. Think of it as an iPhone kiosk. Users will not be 
able to access any functions on the phone outside of the app.

Once I have completed all the development work on the first phone, I 
want to clone this phone to other iPhones so that each is an exact copy. 
Is that possible? Can I create an iTunes backup of the first phone and 
then use that backup to "restore" it to new iPhones?

Second question is in regards to distributing and updating the app.

The app itself is not to be sold through the App Store. My business 
model is based on distributing these iPhones (with the app 
pre-installed). Again, the phone will never be used for any purpose 
outside of my app. The phone will not be used to make calls, but it does 
need to access the internet. Most importantly, my app needs to be kept 
updated. Is there some way to automatically update the app (even through 
a jail-broken means)? I imagine larger corporations have exclusive apps 
that are not distributed publicly and are kept updated. How does that work?

Thanks,
Richard Miller
