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
