What iPhone models does Apple still offer?

I have to go to Apple tomorrow to get my phone checked out because ever since I've gotten the new software, I've been having a lot of problems and my iphone has been having an adverse reaction to it.So, depending on the outcome, I may have to get a new phone. I want to know what iPhone models that Apple still offers because I really want to get the iPhone 5 (not the 5s or 5c).

DON'T BUY APPLE UNLESS YOU ARE A DUMBASS

  • What brands and models of cellphones have metallic casing (beside iphone)? Lot of cellphones are made from plastics like samsung, nokia and others. I know the iphone has metallic lining at its side and its side buttons are also metal which i find really nice and impressive. But i don't like iphone or specifically the ios. I prefer android or WP8. can you name some high end models with these os with a metallic casing or at least lining but specifically metal buttons.
  • How many iPhone models are there going to be? IPhone 2G, iPhone 3G, iPhone 3GS, iPhone 4, iPhone 4S… Don't you think Apple is going a bit too far with the whole iPhone concept? The company have already sold so many of them but, still, they continue releasing new iPhones annually. I have to admit that they are very elegant and useful devices but how long is this iPhone thing going to continue? I mean, will Apple continue making iPhones until all numbers known to man have been used to name new models?
  • How can a chinese company offer free shipping and still make money on ebay? I purchased a charger for my iphone on ebay from a company in Hong Kong. I paid 14 cents ($0.14). Looking at the postage ($26.10 Hong kong Dollars about $3.37 us dollars). It just doesn't add up. How can they sell at a loss? I'm Paying thorough Paypal. They get no financial information from me and it's being send to work so all they have is my name. Http://www.ebay.com/itm/170905507716
  • Does Verizon offer limited data plans? I previously had a DROID X but downgrading in January to an EnV Touch due to the expensive, $30 a month data plan that you had to have with your smartphone. Someone told me who has an iPhone 4 that they don't pay the full cost data plan and I can't seem to find this information on their website anywhere.
