iphoneunlocking.com is a scam, Internet
Whatever you do, do NOT purchase anything from www.iphoneunlocking.com/, and I would be suspicious of similar websites. They promised to unlock my iPhone with downloadable software, providing a 100% moneyback guarantee among other promises. Instead they just took my money. The links to the software they promised were dead, and the support interface linked to nobody.
Sites like this should be taken off the internet by force, and those who secured the domain should be prosecuted.
