If you like the idea of installing more than one ROM to your Android phone, Boot Manager is for you and it is from Init 2 Winit Applications who have developed this great tool. They have now updated the app which is able to provide this to the Samsung Galaxy Nexus which is a very popular phone. This one lets you load up to 4 other ROM version to your phone on the SD card rather than rely on a single ROM install on your phone. Having a the ability to boot from a selection of ROM versions is a great thing when you are testing out new versions of the Android OS. It is an essential tool for those who want to be testing the latest releases and do not want to screw up your phone. This is definitely not for the faint of heart and there are those who feel the need to always download and test the latest build from Google.
If you are one who develops apps for the Android Market, this is a must have tool for you. Support covers a fairly large number of phones and you can refer to their site for specific models. Most of the phones which are support are HTC models along with 4 Motorola phones. The Samsung Galaxy Nexus is the first of the Galaxy line of phones to receive support from the Boot Manager. We can hope that this gets extended to other Galaxy phones such as the Galaxy S II. With Samsung having global sales numbers for 2011 neck and neck with Apple, they are going to continue to grow and deserve to have the Boot Manager running on their popular phones. You can get this one directly from their web site or through the Google Android Market at $2.99.
