Does the SD Increase app actually make a difference? Do you only notice the difference if you use specific apps? Does this harm the phone at all? How exactly does this work and is it a "set it and forget it" feature? Or do you have to do this each time the phone is booted up? Hopefully this speeds up the "Media Scanning" crap that happens when you boot the phone. Sometimes that takes forever. I'm really just looking for a good review about this app, it's pros, it's cons, and any side-effects it may cause.
