Skipping the queue upon arrival to the US? With an iPhone app? They've done it!
Mobile Passport Control (MPC) will allow eligible travelers to submit their passport information and customs declaration form via a smartphone or tablet prior to CBP inspection.
The first trial has started at Hartsfield-Jackson Atlanta International Airport. The experience is limited to US citizens and Canadian visitors, and it's unknown if it will ever be opened to more nationalities—it would make sense for Visa Waiver Program countries covered by ESTA for instance.
Permanent US residents might get included soon.
You won't be skipping the queue entirely, but have access to a dedicated desk where you'll show your mobile voucher—a QR code receipt.
There are a few other limitations: while you can fill your profile in whenever you want, you can only submit your information to Customs and Border Control up to four hours before clearing customs (it then expires).
You also need data access to submit it, which often means waiting for landing (if the airport has Wi-Fi or if you're a cellular network).
Although the app insist that you must have landed, I suspect sending the information whilst enjoying in-flight Wi-Fi works (provided you're within the previously mentioned 4 hours window).
Oh, and the app is not yet on Google Play, but Airside Mobile is working on the Android version (no, there are no Blackberry plans, people, you should just forget that phone altogether, sorry).
The app also plays with the behavior that everyone seems to love these days: taking a selfie, since upon creating your profile on the app, you'll have to add a picture.
I can already imagine those long-haul tired faces.
