If you bought iPhone 4 from abroad, for example via the auction server ebay.com, it is possible that your device is locked to only one operator or another. At auctions or sales, always look at whether the phone says Unlocked or locked. However, even if your phone is locked to one operator, thanks to our instructions, it is not a problem to unlock it immediately.
For those of you who don't know the vocabulary of IT slang, hacktivation is activating the iPhone to access home screen and unlock is to unlock your iPhone to use the SIM card that your iPhone blocked.
!This procedure is only and only for 4th generation iPhones ( iPhone 4) with firmware lower than 4.1!
What will we need
1. iTunes version 10 and above.
Approach

5st step: Enter the password for your Mac and click on OKAY.
6st step: Go to bookmark Log and click on Start TSS Server (if TinyUmbrella shows you that the TSS server could not be started, there must have been an error somewhere. If, despite all efforts, the TSS server fails to start, as in the procedure you must not continue !).

8st step: Click on CMD + Restore (Mac) or shift+Restore (Windows), find firmware 4.1 for your iPhone, click on Choose and then on Restore.

It sucks a bit when 4.2 comes out soon and with <4.1 it practically doesn't sell anymore, right?
so it also works on software 4,1, doesn't it?
it says above that it must be lower than 4,1, so how?
I was wondering if the unlock is working
I'm sorry
so it's nicely written, but the essential thing is missing, which firmware version is this guide applicable to?? I think everyone is wondering if it works with 4.1
So I tried it and it threw me error 1604 :( so it doesn't work :( at least me :)
Hi guys,
I followed it exactly as it is above and now the place (I'm in the UK) is Vodafoneone (I bought it locked from a person who had a contract with Vodafoneonem) pay as you go I have an Orange sim (on contract) – great!!!!! It works!!!! Great job!!!!!
Hi, I clicked on http://www.htcecko.cz/ and there they unlocked my phone for 300 CZK. I just connected it to itunes and it was done. I recommend.
