I have an iPhone 4 16GB (black), and it's already out of contract so I think it's eligible to unlock as well.
Could you please help me to unlock my phone so I can use it with other carrier Sims. I would appreciate it.
My IMEI number is: 012653004673549
Please let me know if you could help me out. Thanks again.
