I had a iPhone 4s, Verizon carrier but i unlocked it for my friend so she can use it in different carrier. However, she told me that she can not use it because it is still locked. Even technical unlocker person can't unlock that cellphone. She gave me $200 on april but I feel like she is lying and want her money back. Before when i gave her a cellphone. Verizon name disappeared on the screen when service center told me it was unlocked. Would iPhone 4s still be locked? And i didn't take out my old sim card so would it work if she put hers?
