You don't 'make' your parents do any such thing that would be rude and selfish. If a simple request is insufficient then go and earn some money and buy one yourself.
The iPhone
The iPhone 4
iPhone, but its very expensive
an iphone for people that dont want to get the iphone because they already have a phone
An iPhone is an iPod Touch (iTouch) with the phone and camera. Thus, an iPhone is already an iPod touch with more features.
Nokia 8800 Sapphire Arte is most expensive phone right now......it has every advance feature a user need in a mobile phone....
depends on the company you're buying the phone from, but usually not.
orange and blackberry
If you have a legal iPhone with ATT service then you already have an unlimited data plan, as the iPhone is not offered without one.
Nope. Got an iPhone thou. Very different!!
Yes. The iPhone 5 already launched September 21, 2012. You forhot the "i" in front of the "phone" in your question, but I can safely assume you meant iPhone 5.
Get an iTouch, or convince your parents to let you have a phone.
