1. I want to root and unlock the BL. Should the order matter. Can i unlock even after root?
A. Any order will do!!!
but since ur r on .62(assuming u dont update to ICS )
then its better to unlock bootloaders first
because then u need to flash any custom kernal and u can root it easily!!!
2. If i want to Unlock unofficially, just to make sure my warranty is on, is there any way I can do other than S1 tool. I also need this method to give me option of relocking just in case i prefer warranty.
A. I have locked bootloaders and i dont have much knowledge about it
3. Is root needed for upgrading to ICS?
A. NO
u can update to ics without rooting
4. Is there a way to come back to GB if the ICS is not good enough?
A. yes see this link
5. What do u suggest me? Root in GB itself, know how it works and go to ICS? Or upgrade to ICS and if i dont like, come back to GB.
A. go to ICS
6. What is the general feedaback or how do u feel about the ICS in Neo V?
A. i love ICS
see my video and u will come to know
it has many new features
