new android user..got a few questions

[fireburst]

Hello everyone!
I have a rooted galaxy s2 (I see the superuser app on my phone) running android 2.3.4. This is a Bell phone. What I would like to do is unroot the phone, then update it to 2.3.6 or wtv update is available through kies (normal update) and then root it again and unlock it using Galaxy_S unlock so I can use it with Fido.
I have a few questions:
Is it even possible to do this?
Can anyone tell me if this is a good method? how to do it properly? or any better alternative methods?
also, if I use this unlock, is it permanent? or do I have to re-unlock the phone every time I loose root/update firmware

ANY help is appreciated, i'm trying to put all of this together and it's not very easy. I bought the phone rooted...but it's not unlocked (as it doesn't work with fido), needeless to say I have no clue how it was rooted and what was used (or if it even matters).

EXTRA infro: (when I press *#1234#, I get:
PDA: I9100XXKG6
Phone:...XXKG2
CSC:...OXAKG6

You don't need to un-root, just flash the new firmware and then re-root. Head over to samMobile.com register, you can then download the firmware along with the flashing program called odin.
Looking at the Galaxy s unlock, it only works on the Galaxy S I9000 and not the Galaxy SII I9100. You will need to find another way of unlocking your phone.

THX! but it does work with sg2 (it says so in the description and in the comments you can people who tried it), but my question is if this unlock method is permanent or not.

It should be permanent.

There are 2 Galaxy S unlocking tools, 1 for the S1 and 1 for the SII. Yes once it is unlocked it is permanent.

You can also check the network lock by typing this into the phones dial pad: *#7465625# ideally all locks should be OFF, but as long as network lock is OFF you should be ok.

yup, it was ON. so I downloaded and tried the Galaxy_S unlock tool and it unlocked my gs2! the gs2 unlock app does not work on my galaxy s2 because it is not GT-I9100, but GT-I9100M..(we have an extra layer of protection). thanks for all the help now it's unlocked!
