hi guys

i have LG optimus p920 3D
S/W ver. 2.3.5 (Gingerbread)
recently i noticed that official ICS software was released for my phone but many of my friends say that Gingerbread better than ICS and advised me not to update the firmware

i want your opinion guys

Install ICS or Keep Gingerbread??????

and one more question :
if i updated to ICS can i downgrade it again to Gingerbread?? in case of i didn't like ICS

thnx
