I have some big news for Motorola Droid Razr users! Boot Manager the app that allows users to boot into multiple roms on the same phone has been upgraded to support your device. Boot manager allows you to install boot roms from your sdcard and boot between them with just a restart. This also allows users to safely test roms being that the main system is left in tact. This is great for the crackflasher who just can't decide on a favorite Rom. You can also sync Sms and phone logs across Roms! I have used Boot Manager in the past and can say that the boot roms feel like you are running the Rom on your main system. You wouldn't even know that the rom is running from the sdcard! The latest version is available for free on the play market or you can grab the Pro version from the link below!
