I have had the Droid X since Dec 2010 and I'm kicking myself for not rooting it earlier. As for my next phone, that's going to be the first thing I do.
I rooted my phone because I was tired of the thing being so laggy and all the BLOAT that Verizon puts on it. Best move I have made. Over the last week I have tried MIUI (Gingerbread and ICS) Cyanogenmod (GB and ICS), SteelDroid version 4.0, and some others...
Looking forward to trying more. I will use my phone as a test dummy for anyone that wants me to. I did brick my phone at one point (stuck at the M) and re-SBF'd it and got it back so I'm comfortable with trying anything.
Just reply to this thread and I will do whatever. Let me know!
