Apple's last new iPhone of 2018, the iPhone XR, is now available for preorder. Although it's not quite as expensive as the iPhone XS ($1,000 and up), the $749 starting price puts it out of reach for many a buyer.

Thankfully, there's at least one deal to be had on Apple's "cheap" flagship. It comes from Sprint -- but stay tuned for iPhone XR deals from other carriers. AT&T, T-Mobile, Verizon and US Mobile all introduced special offers on the iPhone XS and XS Max, so it's quite likely they'll do likewise for the XR.

In the meantime, here's the scoop on Sprint's deal: When you preorder an iPhone XR (64GB), trade in an eligible phone and sign up for an 18-month Sprint Flex Lease, the phone itself will cost you $0 -- you pay only for service.  

That service starts at $40 per month, for a plan that includes 2GB of high-speed data. But Sprint's Unlimited plans range from $60 to $90 -- on par with what the other Big Four carriers charge.

As for eligible trades (for a new line of service), here's the list: iPhone X, iPhone 8, iPhone 8+, iPhone 7, iPhone 7+, Samsung Galaxy S9, Samsung Galaxy S9+, Samsung Galaxy S8, Samsung Galaxy S8+, Samsung Galaxy S8 Active, Samsung Galaxy Note 8, LG G7 ThinQ, Google Pixel, Google Pixel 2 and Google Pixel 2 XL.

It's worth noting that Sprint is still offering this same $0 deal on the iPhone XS (again, with eligible trade-in and an 18-month service plan) -- at least for now.

If you take it as a Big Four-carrier unlimited service plan is going to cost you at least $60 per month, then Sprint's deal is pretty tempting.
