Tried. it doesn't work.
Call T-Mobile and tell them you might be going to Europe in a couple weeks.They will email you an unlock code in a few days for free. Pop in another carrier SIM card from a friend and enter code. Worked for my GS2.

I do this all the time. I don't understand why people would pay for them in the first place! Just call your carrier and tell them you are going out of country and would like to use the phone you have. If they try to sell you international services, just decline and they will still give you an unlock code for free!

Only thing unlocking your phone will do is allow you to pop in a different sim card and use that provider's service with your phone

It won't affect your internet speeds....it typically won't void your warranty (since some providers WILL unlock your phone for you if you're traveling internationally....)....and it won't help you get updates faster .

Just to clear up some of the questions being asked frequently

I got this working on my AT&T S3 !!!!

My phone was rooted, so I restore it to OEM with these directions [galaxys3root.com]

The I went into settings, about device, software update and made downloaded and installed the latest AT&T phone firmware.

Then I followed OP instructions and step "[4] NW Lock NV Data INITIALLIZ" was avail! Confirmed to work on T-mobile $30 plan.

Thanks OP.
