Boot Manager is the first Android Multi-Booter Application! The application installs up to four ROMs to your sdcard and you can keep one on your phone as well to allow you to boot up to five ROMs and switch between them with just a reboot. This is the must have application for any flashaholic and will finally allow you to keep up with those nightly builds we have all come to love or just boot your favorite ROMs from your favorite developers. The application is great for developers as well since you now have 5 slots for testing ROMs. BootManager is only officially supported on the original Motorola Droid and the following HTC smartphones: Droid Incredible, Thunderbolt, Vision, EVO 4G, Inspire 4G, Desire and Desire HD.
Boot Manager is available for $2.99 on the Android Market.
