Samsung Galaxy S2

[01484]

I bought a samsung galaxy s2 off a friend and its on the 2.3.6 version. It has been unlocked (still has t-mobile branding on it though) and rooted. What i want to know is if i update it via samsung to the latest software which is ICS 4. something would the phone be locked to t-mobile again? i know i will loose the root access im not bothered with that all i want to do it update it to the latest software, but afraid of it being locked back to t-mobile.
Thanks for your help and time. :smile:

I really do not see why you would be losing the sim unlock. It is just an update that they provide themselves. The time you may lose the unlock is when you restore back to stock but you should not be losing it when you update.

Root will be lost for sure but custom recovery and superuser takes care of that very nicely and quickly.

I would personally just do a backup and do CM10 because it is jellybean and it works lot better than ics like light years better!

I am pretty sure you will lose your unlock. Happened to my Captivate.
