Hello, I have an iPhone 6 on AT&T and on Nov. 21 used the site att-iphone-unlock.com to do it for me. I chose them after quite a bit of research They said it takes 1-10 business days. I am leaving the country next Wed. so am getting real anxious about they'll actually be able to come through. Does anyone have any experience with them or other services? I am hearing that there are issues with unlocking AT&T phones? Why does it take so long and what is the actual behind the scenes process of unlocking the phone?
