How to buy an app on the apple store?

Every time I try and buy an app a little nonification message pops up saying " payment information required " When I press continue it takes me to a page called " Account settings " And it names a bunch of payment types like Visa, Mastercard, Amex, etc I'm supposed to choose one but I actually want to pay with paypal but if i can't, I COULD pay with one of the cards but it asks for the card information like its number & security code ( As expected ) but when I asked my friend (who has owned an Iphone for many years) he told me he has never has or had to go through all that when he buys an app so I thought it was kinda fishy but in conclusion, my questions are Do i fill out the card information without worry? If I DO fill out the card information will I be able to purchase the app from there? & is it possible to just pay with paypal?

Is my iPhone 6 useless now? What do I do?

I just bought a gold 64GB Sprint iPhone 6 from someone on Facebook. Before buying it, I looked up the IMEI on both Swappa and CheckESNFree. It popped up as clean. We met up twice because she didn't have the box, case, and accessories during the first meet; she was very chill. She even had kids. There was no activation lock or anything. After a day of messing around with it and trying to activate it, I couldn't because it was still activated under her account. She talked to a Sprint rep and they said it wasn't activated under her account. After restarting the phone, there was Sprint LTE services and incoming voicemails. But from her number, her account. I've turned off the data (because I'm probably using hers) and tried contacting her, but she hasn't replied? What can I do? Have I been scammed?

IPhone won't connect to beats pill?

I have an iPhone 5s and I have a beats pill. It's just the white pill, nothing special about it. The problem is that when I go into my Bluetooth and try to connect my iPhone to my pill, it keeps saying "make sure beats pill is turned on and in range". It is turned on and in range. I reset my pill and my iPhone. Still nothing happened. I also try putting my pill in pairing mode. It keeps saying connection failed. My dad can connect to it with his android. But I don't have an android and should need to have one when the box clearly says its compatible with apple products. I know I can use the aux cord to play my music through the pill, but I should have to do that. My Bluetooth should work. This product was expensive and it's failing to do its job. Wether it's the phone or the speaker. But, if you know how to fix this, please let me know.
