Absolutely!!
I held off for a long time. But last week I rooted and, VOILA! everythign works as it should.
no more reboots
GPS locks on instantly
everything is snappier and the UI is way better
I'm running the BAMF 2.1 ROM
be sure to load the MR2.5 radio too otherwise you'll have no radio.
really simple to do and well worth it!
