I really don't think that you need to worry about the Prevail being updated anytime soon as far as Boost goes . All of the apps you install will still be updatable after rooting .
As for rooting , go for it ! You won't be sorry . There are apps on the Market that will allow you to move most of your apps to the sd card too . Some of the ROMS here in the Forum even have that feature included in them .
If you need to return your phone for warranty issues , there's even a fix for that called Odin . It will let you return your phone to stock .
If you are interested in a new ROM , I
HIGHLY recommend either Hroarks CM7 or Bloodawns CTMod . CTMod 2.5 is very stable and user friendly , 3.0 is still in the beta stage (be aware of that) .
CM7 is a ROM for the person who enjoys a challenge . It has a lot of features that CTMod doesn't .
The Skater even has his own ROM out called "187MoD-HoneyBread4 + [Kernel] Genocide 2.6.35.14 For Non-CM7" that runs great .
You have a lot to choose from and they are all excellent ROMS .
Before doing anything , I ask you to please read the threads . There is a wealth of info in them .
Last but not least .... welcome to the Forum !
