So I just bought a Galaxy S8, and this is my first phone ever. Not full price, but I got to play monthly payments obviously. But i'm curious if I could switch to an iPhone later down the road. Like what would the requirements be to do that switch from Galaxy S8 to iPhone?

Ebay buyer not returned my item back?

Basically on Ebay UK, I selled my Iphone but the seller opened up a not as described case against me and Ebay decied in there favour I knew that was untrue so I changed the return address with incomplete information but he still sent the item back and got a refund!

I have provided him now with the correct address as I managed to appeal it with a lot effort but he is not messaging me back or anything to send the item back.

I have his address from when I sent it, what can I do?

Added (1). I went about it the wrong way as he was lying but how can I recover the phone as I don't have to pay Ebay for reimbursement but the buyer now has the money when Ebay refunded him and now he has my phone!

My iPhone 4 will not charge? - 2

I've had this iPhone 4 for about a year and a half. My Father got for me from Good Deeds, a used product store. At first, the phone charged fine, but now at this point the phone will not charge to ANY outlet. Not even hooked up to computers. I've tried all the outlets in my house, school and friend's houses and it will not work. I even bought a new cable for it because I thought the one it came with didn't work or just worn out. The new cable doesn't work either. Is there something wrong with my phone battery? The cable I'm using or the phone? The stupid thing about it is when the phone dies, it charges normally, but as soon as it turns on, it doesn't charge anymore. It just doesn't take any outlets and the outlets are fine. Can someone please help?
