Can i use my iphone 4s on the airplane?

I'm flying jordananian airways next week and wondered if i can use my phone? Am i gonna be able to have internet?

You can, but you'll have to turn it to airplane mode, which cuts off the signal. Unless your flight offers Wi-Fi service, you will not be able to access the internet on the plane.

I was told that my IPhone 4S would interfere with the plane's electronic equipment.
It's their plane, their rules…
ask the airlines

You can use it only in air flight mode. As for the Wi-Fi, you can ask the airlines if they have it available.

You will not be able to use mobile data (3G/4G/LTE). They require you to shut it off during taxi/takeoff and landing because it interferes with the navigation system. You can use it in between with it being on airplane mode (watch pre-downloaded movies, listen to music, play games, etc.) After the plane ascends to 10, 000 feet, if they offer in-flight Wi-Fi (such as GoGo,) you may use it.
