My phone upgrade is coming up. GS3/4 or Iphone?

My upgrade for a phone is coming up soon and I'm having trouble deciding if I should get a Galaxy or an Iphone. I'm in highschool and have a job so i'm going to be using the internet and e-mail a lot. I know how to use an Iphone extremely well because all of my friends have it so getting used to it would be no problem.

Samsung Gallaxy S4. I heard they are better than Iphone 5. I have a LG Motion 4G

  • Will Tmobile Iphone 5 work with my GS3 Internet plan? My internet for my GS3 is just listed as Preferred Androind Unlimited Web Only. If I pop my sim into a tmo version iphone 5, will internet work on there as well? I'd think they use the same 4g internet that comes from the towers, so it would only make sense this works the same?
  • Which Phone to get? Iphone 5 vs HTC One X + vs Galaxy S3 vs GS3 mini? I'm getting an upgrade at the end of the month and here are my phone choice Iphone 5 HTC One X + Galaxy S3 Galaxy S3 mini The One X + will be coming out soon and it looks really great so I can just wait for it if i have to. Can anyone list the pros and cons of these phones? Thanks. Galaxy is the highest rated phone, but one x + isn't out yet:/ The one thing is to me that galaxy s3 is a bit too big:/ thanks god one x + is a bit smaller
  • When I upgrade my iPhone, can I upgrade to the same phone? I have the iPhone 4S and my upgrade is soon, but I don't want the iPhone 5. And I have some little cracks and my speakers are weird. So when my upgrade comes can I just get the same phone that I have now?
  • Verizon SIM card in spring gs3? So my friend is willing to give me her Galaxy s3 when her upgrade comes but she has sprint and I have a verizon iPhone 4S sim. Will I be able to use my sim in the gs3? If so how? Can I do it without unlocking or do I need to unlock the Gs3
