Check iPhone before you buy it!

Not everyone have enough money to buy new iPhone or simply don't want to spend that much cash on phone so almost as often as new phone is bought, old one is sold.
But one warning - always check is this phone lost or not - one of best services to check warranty and Find my iPhone for free is in the link.
At the moment you can only check Find my iPhone status in basic range (on/off) but on their official forum is information that in near future this service will be expanded with lost/stolen status so it will provide maximum security agains thiefs who try to sell stolen iPhones.

Also I want to inform you that new update of iOS  (9.3.5) is essential for security of your phones - it patch problem with  susceptibility for hacher attacks!
