Been shying away from rooting my DX until recently. Just too many programs loading up when I boot, so I rooted using z4Root. z4Root made it so easy, not flawless, but that's another story for another thread. Anyway, here's my new favorite 5:
1. Titanium Backup - Backup is exceptional, but freezing apps makes this worth rooting.
2. Droid X/2 Overclock - So much more than just overclocking, if you're rooted, got to take a look at the extras.
3. JustPictures - You got photos, then you need this app.
4. Smart Shortcuts - Sort of like nesting folders, but way better and cleaner.
5. Here's where it gets hard. There are many more apps that I use daily and to put one here without putting the others in perspective would be a disservice to all the apps I use not on this list. So I'm reserving number 5 for all of those apps I use. Cheating I know, but my list is only 5 items, so I'm still within the rules.
Ok, I sucked out on the last one, but come on, you know what I mean.
