Trampoline is the codename for the iPhone 5's OTA Update Enabler. iOS 6.0 on the iPhone 5 apparently included a bug that prevented OTA updates from occurring properly. As a result, Apple made the OTA update process a little less straightforward.
Trying to perform an OTA update informs you about the updater app, and how to obtain it.
Process
- Spawn by update daemon (causes elevated privileges)
- Mount Disk Image
/Applications/iOSUpdater.app/iOSUpdaterHelper.dmgat/Developer - Copy contents off (essentially
cp -r /Developer/* /) - Reboot
- Daemon runs and patches files
- Daemon deletes Trampoline
- Reboot
iOSUpdater.app Notes
- The app can be installed on a device via iTunes.
- iOS Updater can't be deleted on the device, but can be removed via iTunes.
- The app appears to require elevated (root) privileges.
- iOS Updater is deleted on successful update.
- Among with iOSUpdaterHelper.dmg, in iOSUpdater.app, there is its signature. This prevents hackers from replacing it with an unofficial image.

iOSUpdater.app on SpringBoard
