Any idea? Programs already tried greenpoison and ultrasnow. iPhone firmware is 4.2.1

I didn't know you could unlock carriers. I know you can jail break to get free apps and shit.

Don't do that.
You're on a contract.

Breaking that contract is not a very legal thing to do.

PS. Buy a new phone.

You can just call your provider and tell them to unlock it, it's free.

Not if you're in a contract.

I was in a contract and called Telstra who put me onto APPLE. All telephone companies go through Apple's system. Apple don't give a shit if you're contracted or not.

Wow, really? It honestly surprises me to no end that Apple aren't milking all the money they can (via exit fees) from this, lmao.

The iphone was found, not on a contract that i know of

carriers dont really care if you unlock iphone 4's even if your on a contract, as you still have to pay them the monthly repayments

Hock it if you can't unlock it.

you can unlock your iphone..there are many software available to unlock iphone and my friend unlocked it by remote unlocking..there are many online providers who provide the service..one of my friend got unlocked his iphone from prounlocking by remote unlock..and here is the instructions
1. Wait for an email saying your phone has been activated or remotely unlocked.
2. Install the latest version of iTunes.
3. Make sure your Apple iPhone phone software is updated to the latest version
using the iTunes software.
4. Connect your Apple iPhone to iTunes with a NOT ACCEPTED SIM card.
5. Wait until iTunes detects your Apple iPhone.
6. Disconnect your Apple iPhone and reconnect it after 10 seconds.
7. Your Apple iPhone is now unlocked.
and the important thing remote unlocking is available for some country and network providers only so if you are interested you can try from them before that see whether remote unlocking is available for your country and provider..

10 Months late but thankyou =)
