[Q] Unlock SGH-I757M - Galaxy S II Q&A, Help & Troubleshooting

I did a lot of research on this site and on the internet, but I could not find a way to unlock my Samsung Galaxy S2 SGH-i757m from Bell.
So far, I have learned how to root the phone, how to flash the phone and how to install different ROMs.

Is anyone here know how to unlock this phone? Please give me some hints. Thank you in advance.

Galaxy Ace with Orange in Spain

Hi to all!
A friend have the Galaxy Ace, from Orange in Spain. I want to unlock it and root it to flash an stock or CyanogenMod.
I see that SuperOneClick can root the device, but I don't know if I can unlock the net restriction to unlock it.
Any clue to make this possible?
Thanks !!!
You may head over to jcmaster's unlocking tutorial but be warned, anything to do with unlocking may turn the phone into a useless doorstopper.
Now I have rooted with SuperOneClick. Now I need to unlock the SIM Lock of Orange. I need it to flash a new version of stock firmware?
By Kies, I can't update the phone.

I bought this phone in another country, and I'd like now to use it with a sim card from another country.
How can I unlock it to use it with other sim Cards?
Go to xda front page and look new from about first three pages, there you should find app that generates unlock codes
Sent from my sgs2 running cm9 using xda app
I downloaded the app to Unlock the Galaxy S2, but it goes on through five steps from 0 to 100% and tells me that it can't find the code to unlock my phone.
I think maybe it's because it is a S2 GT-i9100G
What should I do?

[Q] Can I unlock a NET 10 Galaxy SII for use with another carrier?

I am wondering if a net 10 Samsung Galaxy SII (sgh-s959g) can be unlocked for use with another carrier (t-mobile specifically)?
Would it have to be flashed with new software first?
Has anyone here done anything like this?
Thank you for any help or suggestions.
If it's not in here, then I guess you'd have to try galaxysim unlock.
You need to be rooted, of course.
