Iam not cynical for being rooted...it's just that I don't know the entire process as I never really felt the need of it...but since I hear everyone gets rooted, the thought did cross my mind....again I don't know which rom to choose n all...that's it...just a newbie to root I suppose...
Cool, nothing wrong with that. Everyone starts out as a newbie. I'm not an expert by any means but over the past few years I have successfully rooted several phones and I can tell you the Galaxy Nexus is one of the easiest. Also, just because your phone is rooted, doesnt mean you have to use a custom rom. It's perfectly fine to just root your phone to gain access to be able to do those things you wouldnt normally be able to do while keeping the stock rom. Just dont accept any OTA updates or you will lose root and have to do it again.
Two things I would recommend. There is an app in the Play Store called
All About Root It doesnt "do" anything, its just a good source to read about rooting.
Second, if you want to root your Galaxy Nexus, I would recommend the
Nexus Root Toolkit by WugFresh. It's a super great program, very easy to use, every button pops up and tells you exactly what it does and gives you the option to continue or cancel so you dont have to worry about pressing the wrong button and doing something you didnt want to do. I used this program to root both mine and my wife's GNex and it worked perfectly both times. You can even use it to make a backup of your apps/data so that when you root it and it wipes everything, it can all be restored. This is what I had to do for my wife's phone and it worked great. Then once you're rooted you can enjoy the use of apps like Titanium Backup (get the pro version ... def worth it!) and then you can get the new Gmail 4.2!
That's it! It's simple and easy. I would say read the info in that app and then check out the Nexus Root Toolkit and just click around in it. Like I said it tells you what everything does so you cant mess anything up and you dont have to worry about a custom rom if you dont want to. The advantage of a custom rom is additional features that the stock roms dont have. I'm currently using one from Code Name Android that is based off Android 4.1.2. You can read about it
here if you want. Feel free to PM me if you want. I can help answer any questions you have about any of it.
