I have an iPhone 4 I need to unlock for T-Mobile. I was able to cut my SIM card to be able to fit but I can't seem to find proper nor reliable instructions in unlocking my phone. I've tried YouTube and researched on Google for about 2 hours now and can't find any info that seems legit or able to actually work now. I'm debating on going to a shop that can do it locally for $30. But hopefully maybe you guys can help/guide/link me to proper instructions with what I have. iPhone 4 Version: 4.3.3 Firmware: 04.10.01 Let me know, thanks.
