We received unofficial information, that the newest version of Apple system called IOS-8 has a bug problem which can result in relocking your iPhone even after it was unlocked.
The problem is that if You unlock your iPhone and than try to upgrade it by iTunes the sim blockade might return.
The best solution to avoid this is to upgrade the system before the unlocking process.
If You unlocked your iPhone and You need to upgrade it right now, please do this by wi-fi not iTunes.
The problem is caused by the system not our service, so please don’t make any complaints to our company, we are not resposible for the relock that might appear.
