I used this very simple process to unlcock my o2 S2 a couple of days ago

    I did this the day I received my S2 all I used was a little thing called GOOGLE.

    Cool, I'd be interested to hear if this works well for everyone. But think i'll buy mine unlocked and debranded anyway.

    You forget to mention the phone has to be rooted and the only way to do that is flashing a custom kernel which roots phone at same time. (unless you have a pre-release S2 in which case you may be able to get round this).

    So easy to say its simple without giving detailed steps!!! Also its not a deal.

    o2 would have got you an unlock code for free too if you'd asked them.

    Yea Ive done it it works, but its not something that should be posted.

    Basic steps are:

    1. Install custom kernel which installs recovery software and roots phone (Guide on XDA site with list of custom kernels).
    2. Download Chainfire unlocking app from market.
    3. Run app which should give you unlocking code, takes few mins.
    4. Restart phone with sim from different network. Try the code once and only once.

    Also gives you option to install custom ROM now phones rooted but I havent bothered as S2 stock 2.3 rom is fine I think.

    Edit: Also worth noting this probably voids your warranty as you've flashed a custom kernel. Unless you flash stock kernel back, although not read into that.

    I dont have an account with o2 and didnt need one as i`m on a three contract, this was pretty much instant. and i didnt feel i needed to list in detail what needed to be done, as that`s the whole poing of providing a link?

    maybe this was not a deal (i was unsure what section to post it) but i just want to give them some extra support as they have worked to make a tool that helped me.

    sometimes its nice just to post things here you find "MIGHT" help others.

    Yes there are other ways to unlock. but this just gives people another option.

    Thanks for all you comments.

    would it or anything similar work on the new xperia mini pro ( SK17i) ?
    any simple way to root the SK17 without jumping through all the custom flashing hoops?
    I don't particularly need root just need a network unlock to use alternative network sim.
    Most online unlockers want £25-35
    cheers

    No. Unfortunately not.

    You could see how much your network would charge?
    I got my Arc unlock code for free from o2.

    I've not used this myself but from what I've looked at you could possibly unlock it yourself

    Best to ask on their Forum first though

    I tried but Chainfire app, on a SG2 locked to Orange but it couldn't find the code.
    Does anyone know why, and if there's any other way of getting the code?

    Is the phone rooted? If not then thats why it didnt work. If it is reboot and try app again. If still no joy try the manual way looking at the .bin file as posted here:

    Where was your phone made? what does it say under the battery
    mudddy
    It was rooted but only tries that app once.

    I managed to unlock it using an alternative unlocking app (the old galaxy S one which now works for S2).

    I've sold the mobile to a relative, so no longer have it.

    I got my SGS2 on Monday and used the above link and when you submit the request it states that it will take 28 days for the request, but I got an email thanking my for my request and I should get a reply within 48 hours.

    Well yesterday I got another email which contained the unlock code which worked and didn't cost me a penny, so thanks spruceyb :)
