Using a preowned Iphone for Wi-Fi device only, problems I might encounter?

Well my brother gave me his older Iphone to use and I only used it to browse the internet, skype and google voice. Only problem I encountered was at first when I tried to DL a app and it asked for "Apple ID Password" in order to DL any apps, well him being my brother he gave it to me and that was that. Anyways I lost the phone and now thinking of buying another one off a person and was wondering what I need to ask or do in order not to run into this problem again and also would it be better not to get a Iphone?

If you just want a Wi-Fi device, you're better off buying an iPod Touch (which is the exact same thing as an iPhone, but it's not a phone)

They're cheaper.

A new phone won't give you problems

  • Will my jailbreak on one device transfer to another device via iTunes? So I bought an iPhone 5 today and I'm afraid to sync it to my Apple ID/ iTunes because my 8GB iPod is also synced to that iTunes account and its jailbroken. I don't want my jailbroken iPod to affect my iPhone 5. Will it affect it? I don't think it will but I just want to make sure before I sync it for the first time.
  • What stores might have the iPhone 5 in stock? What stores (AT&T, BestBuy, etc.) do you think have the best chance of having the iPhone 5 in stock. When will Apple Stores have regular availability?
  • How do you stop calls coming from one device coming to your device from iCloud (apple iPhone)? I'm 13 and i don't have a credit card so i use my mums account and since my phone and her phone has the same icloud, her calls come into MY phone and i've tried making a new apple id but it won't work so how can i stop it (i've already logged out on my phone) so how can i stop it?
  • IPhone 5c users or any other iPhone model users. Screen clicking issue. You might have it as well? My iPhone 5c screen on the lower right is making a clicking noise everytime I press it, same goes on the plastic back near the iPhone logo! I just got this phone brandnew weeks ago. A lot of people are having this issue at the moment on their 5, 5s, 6 and even the 6s! Idek the cause why its making this noise. Never dropped this thing. Just wanted to ask if you're experiencing the same. If it weren't for my OCD i wouldn't have noticed i've had this thing for weeks now lmao
