I think you do. Although, when you turn it on for the first time, there are some default apps that come with the phone.
You buy the iPhone app
If it's on the thing you buy apps on, then probably. If not, then no.
Yes, it's called the App Store, and it comes standard on every ipod touch, iphone, and ipad.
Buying a phone like iPhone is dangerous, because it has a low battery life and low signal capability; buying a phone like this can put you in danger when you are in an emergency situation. AND it is battery is not replacable by you. I am not saying that you should buy iPad; but whatever you do, avoid buying iPhones. iphone 4 and ipad both are different electronic devices....ipad is tablet and iphone 4 is a smart phone ....apps for for both the devices can be transfered from one another and some of the features are also same but on the whole they are different sites....................................................
no you cannot use ipod and iphone apps on itunes, but you can buy the apps on itunes and put them on your ipod and iphone
To use apps you do not need internet, but you do need internet to buy apps.
There are a wide number of apps available on app store. Some are available only for iphone and some especially for ipad. Some are compatible with both. If you are choosing a free app you can just download and use it.
Apps are different games created by different companies. Some apps cost more than others. The more advanced version of the app you want, the more it will cost. I would recommend downloading the lite (free) version before you buy the full version (that costs $$$).
Should you buy an Ipad as well as an Iphone? Answer: This is completely up to you, the Ipad is a wireless device so it doesn't make sense to spend money on two phones.
No. Your iphone should be 3G version or later.
On the App Store. It should be installed on your iphone right after you buy it. The iphone should be at least 3G or later.
No, you just need to free download iTunes and then use it to buy apps. iTunes is free.
