no you have to submit them through apple
Download installous on iPhone (In the IPhone Store)
download them from the apps store
The App store :)
By the time I answer this question there are ~285,000 iPhone / iPod Touch apps on the iTunes App Store.
Of course you can in the app store there are tons of free apps
There is an App Store on every iPhone. You download them from there (:
There are hundreds of millions of free iPhone apps of the App Store, so it would be unnecessary to list them all. You can access the app store and look under "Free Apps" to browse them.
The apps from the Apple Store will only work with Apple's iPhone and iPod Touch.
apps from an itouch, iphone, or ipad can very. check the app store to see all the apps
I would believe so, it can be difficult to unlock your iphone though but the iphone is exclusively at tmobile in Europe.
Although iPads can download apps made only for iPhone/iPod Touch, the iPhone can only download iPhone or iPhone/iPad apps. Apps made only for the iPad do not appear on the App Store. Luckily most of these apps have an iPhone counterpart such as Angry Birds (iPhone) and Angry Birds HD (iPad only).
These easiest answer to that is the app store that is actually on the iPhone. There are a lot of magazines out there that will tell you what the coolest apps out there right now.
