I was on the Fence TOO
please read
I was on the fence too... But I am SOOOO glad I did root... I cant imagine still using stock sense (which wasn't to bad, but NOT basic android the only Straight UP android phone is the Nexus)... Now I am running CM7; it gingerbread 2.3.3 with some extra goodies and to top it off its STABLE! again... you have def come to the right place for all of your questions though... this is the best and most respectful and helpful forum site on Android out there. Possibilities are endless.... get rid of your crappy bloatware thats taking up extra space on your phone, get a free wireless tether

im just saying, I am glad I did and I quarantee that anyone you ask would say the same thing.....
HERE ARE SOME SERIOUS WORDS OF WISDOM: if you decide to Root. you MUST read, read, read, and read some more; then after that, research and read even more on ROMS and MODs. one thing that is very frusterating is people that don't read through a whole thread first to see if the answer is there to a question they may have.... I have litteraly seen someone ask a question that was already asked AND ANSWERED on the page before... now to me that is really lazy (all they had to do was go one page back and look)... I am just trying to give you some noob advice... we all started at the bottom and we all learned from trial, error, and great help from good peeps in this place... I can def vouch for
Wanda,
ZeroNeck and
PvilleComp; any advice they give to u will be reliable and you can count on them *and me too.
if you root, first get clockworkmod *free version app, Root explorer or SuperManager (free). and Titanium App *free version.... these are absolute must have apps for any rooted phone user... they will save your life... YOU HAVE COME TO THE RIGHT PLACE IF YOU SO CHOOSE TO ROOT.
If you don't want to root you can always DL a custom home launcher and cutomize your phone too.... I use ADW EX and another very popular one is called Launcher Pro (get the paid one too for all the best stuff), another must have non-root app is astro file explorer app.
You have def come to the right place, thats for sure... and Tapatalk app allows you to keep in constant contact with these forums and other sites forums on your phone... I cant live with out it

sorry for the rambling... I could talk for ever

Here is a shot of my HomeScreen and my Splash screen of a Rooted Phone customized ADW EX icons ... good luck and keep us posted
