Re: {GUIDE} Install ICS ( Ice Cream Sandwich) as well as root Arc S , Ray and Neo V

Hello everyone!

I don't know if my question has already been answered so I'm sorry in case it has.

I own a Xperia Arc S and even though all the pros and cons users have been reporting I would like to try ICS myself but it hasn't arrived it to Portugal...

My phone is "operator locked" (Vodafone) which means I run their custom rom; also, in service -> configuration it says "rooting status: bootloader unlock allowed: no".

My question is (before getting in trouble lol) is it safe to flash my phone to the generic ICS version anyways even with these drawbacks? And then is it possible to go back to GB or get the official portuguese ICS version when out?

thank you in advance Slightly smiling Face
