Yeah, but as i said, i totally new to
Android. If i do something wrong, i need to be good at tackling the situation. To b precise, i bought my phone on 25th Oct, and we still havent seen 25th Nov......u can see how new i m. And btw, let me also mention that this is "My First Android". SO i didnt have experience in any such device prior to this.

I remember the first time i flashed my phone using the Odin and the 3 keys combo did not work ( i could not make it work because of "my" inexperience) and i was scared for having an expensive brick in my hand !

(plus the looks my wife was giving me were not that very nice)

Actually you are correct ...enjoy the default ROM for atleast 1 month and then start playing around - else you will NOT NOTICE the difference in the stock ROM and Custom ROM
I would suggest you to to do the following things (in that order)
1) start visiting the XDA section for 15 - 20 minutes everyday and read a lot (tutorials, to do things etc)
2) See what all is being developed for your ROM
3) Learn - How to root your phone
4) Post rooting - Install few small apps and themes (baby steps

)
5) Learn - how to install Custom ROm
6) Learn how to make a nandroid backup
7) Learn - how to rescue a SOFT brick (you will know the difference between soft and hrd brick by now

)
8) THEN ONLY venture and try out custom ROM
All the best for your Android Journey
