Moto Droid RAZR
I love the features of handsent but hate the UI, so I use the stock sms app.
HTC THUNDERBOLT Rooted / Perfect Storm 1.2 ROM / Overclocked @ 1.80GHZ
Evolution : Droid 1 - Incredible - Droid X - Thunderbolt
I also had it on my D1 and I still prefer it on my DX... if you don't like it, you can always uninstall, no harm done!
