【Mission XXX Impossible】

The Mission XXX ImpossibleiPhone X will finally be available for pre-order on Oct. 27 — but if you're part of Apple's iPhone Upgrade program, you can prep for that process a few days early, starting now, and save valuable time.

You can apply for pre-approval using the Apple Store app, taking care of the selection process for all of your iPhone X particulars before the pre-order period opens. That means all you'll have to do when the clock strikes 12:01 a.m. PT (3:01 a.m. ET) Friday morning is hit one button, saving potentially thousands of spots in the pre-order queue.

The iPhone Upgrade Program allows you to take out a loan from Apple to pay for your device over a 24-month period, with an option to upgrade to a new phone after 12 payments. The pre-approval process will give you a chance to be approved (get it?) early for the loan you'll need to finance the phone — it's not skipping the line, you just won't get bogged down once the phone is available.

You'll be able to choose between the 64 GB iPhone X for $49.91 per month, or the 256 GB version for $56.16 per month. The plan also includes an AppleCare+ membership, and you'll be able to trade in your old phone via mail using a Trade-In Kit, which means you won't have to physically visit an Apple Store to return your old device.

The whole process takes only a few minutes, as we learned here at MashableHQ.

This is one pre-order event you won't want to miss. The iPhone X's production reportedly experienced severe issues that limited the initial shipments to just a few million units to fulfill the estimated 50 million pre-orders — so your spot in line counts. If you want to get your hands on an X at its Nov. 3 release (or before 2018), pre-approval could be one of your safest bets.
