I just picked up two Hydros from a Reddit user (thanks /u/scott992) and went through the process of rooting following these directions: http://forum.xda-developers.com/showthread.php?t=2307306

After successfully rooting both phones, I downloaded a program I've used before called NoBloat Free (Google Play Link).

With the software, I deleted a lot of un-used bloatware and disabled a few other processes. The Backup and Delete feature is nice, just in case something bad were to happen with removing an app.

The list of apps I successfully removed:

Activation - com.sprint.dsa (Disabled)

BoostZone - com.sprint.zone

Eco Mode - com.kyocera.ecomode

Google Play Books - com.google.android.apps.books (Disabled)

Google Play Magazines - com.google.android.apps.magazines (Disabled)

Google Play Music - com.google.android.music (Disabled)

Mobile ID - com.spring.w.installer

Music FX - com.android.musicfx

Preferred Activity Setter - com.sprint.w.prefact (Disabled)

Sprint Installer - com.sprint.ce.updater (Disabled)

Swype - com.swype.android.inputmethod

As far as if this will have any benefit to the performance of the phone, that's hard to say. But, it did clear up some space and got rid of quite a few annoying icons. I'll update this when I find more that I can safely remove.

If you know of anything that I've missed, let me know, I'll try it and add to the list.
