In just a few days, carriers and retailers will open iPhone X pre-orders. As many of you probably know by now, iPhone X price starts at $1,000, which is why some carriers plan to sweeten their deals with some freebies or discounts.

US carriers Sprint and T-Mobile have already announced their promotional offers on the iPhone X, but there are many others that would like to woo new customers into buying Apple's new flagship.

Unlike some network operators that decided to discount the iPhone X if customers sign up for long-term contracts, Vodafone UK and maybe other carriers as well, will offers some free accessories instead.

Apparently, the first 1,000 customers who pre-order their iPhone X units via Vodafone UK will receive Apple's AirPods for free. Keep in mind that the offer is by invitation only, so you'll have to register your interest to purchase the iPhone X, and if you get an email back that means you have been accepted in the promotion.

Only customers who place an iPhone X pre-order at Vodafone UK between October 27-30 are eligible for the AirPods promotion. Your free AirPods will arrive after December 4 if you are among the first 1,000 customers who pre-ordered the iPhone X.
