Please reply As soon as possible and please be entirely certain with your answer cos i don't want to spend 750 euros on a phone i can't use

There's a specific cell/mobile phone category under the CONSUMER ELECTRONICS section.

Leave the CARS & TRANSPORTATION section for questions about cars & transportation.

I would ask them in the apple store there, especially with a specific question like this one

  • Which iphone should i buy? Should i buy one or an ipad? Pro's and cons of an ipone? I'm 15, and I use to have a phone but I got really bored with it so I got rid of it, I don't want to get an iphone then get bored of it do you think i will find them boring. How much credit internet should i get for my plan? People of said get a iphone 4 or 4s coz the iphone 5 doesn't charge properly, so I don't really know? But I want to get an ipad and really can't make up my decision, which one is better in the long run?!
  • Which camera should I bring? Studying abroad in London/Travelling Europe? I have these options: a DSLR Nikon camera, a Sony videocamera (small), or should I buy a digital camera? In addition, i'm bringing my iPhone 5s, which has pretty good quality as well. I'm just afraid I'll lose my DSLR, should I buy a digital camera or take the small videocamera? Suggestions? I will be studying for a semester in London and traveling to a few countries in Europe as well.
  • What to turn off on your iPhone when going abroad? I'm going away today and i need to to know what to turn off so I'm not going to charged AT ALL. Every last bit please! And also if i connect to a free Wi-Fi abroad will it charge me? And what does it mean by in notifications where it says sort apps "manually" or "by time"?
  • What should I turn off/on on my iPhone when travelling abroad? I'm going to Germany for a few days and I'm taking my O2 Pay and Go iPhone5 but what settings should I turn on or off so I don't get charged a stupid amount or use all my top up money? I'm guessing data roaming should be turned off for a start. I do want to post pictures while I'm there though too, should I only do this when I can find a Wi-Fi signal to connect to?
