Distributing custom updates for iPhone

Question

I am using an ad hoc distribution to run a beta test program and have encountered several problems distributing application updates. The only way I was able to get the application update on the device through the ad hoc distribution is to first uninstall the application from the device and then install the update. This adds extra steps for beta testers and erases their app settings.

Is there a way to install a special update without removing the application from the device? If not, is there a way to save user preferences for the application?

Thanks for any help. This is a huge disappointment right now.

I am sure this is your version number. The first time I did a special update (as opposed to the first revision), I forgot to increase the version number in plist.
