No; the best you can do is download other applications with their own built-in keyboard, but that keyboard will only function within that app (it won't be system-wide). Unfortunately, Apple has restricted this functionality from the app store.
If your iPhone is new enough to support AirPlay, you can mirror your screen to your computer and record it from there. For windows you would need to get an AirPlay receiver and if you have a Mac then it is already built in to use.
You can not change the touch screen sensitivity on the iPhone.
That requires jailbreaking to put widgets on your iPhone. Currently there is a tethered jailbreak for iPhone 4S But it i highly recommended that you don't jailbreak.
Update to iOS 4.0.1, then go to wallpaper and change lock screen wallpaper and home screen wallpaper. It wont work for iPod touch 3g and under and iPhone 3g and under because apparently it will slow it down all the new features.
One of the many features that iPhone 3G owners wish they had since the newer models of the iPhone have came out is the ability to set a home screen wallpaper. With the phone as is, this ability is impossible. However, jailbreaking the iOS software can give you full potential to start using home screen wallpapers. Jailbreaking is easy and only takes minutes, but be aware that doing so causes your warranty to be void.
Yes , but not a slide out keyboard. It has an integrated qwerty keyboard on its touch screen which appears whenever there is a text field ( where you can type) whenever you press it.
For all I know, you must 'Jailbreak' it. I think there is a way to screen record using a capture card, but I am not sure!
The iPhone does not have a physical keyboard. It is a keyboard that pops up on the display when you need to type something in and you type by touching the keys on the touchscreen sensitive display.
A virtual keyboard differs from a touch typing keyboard because a virtual keyboard is on touch sensitive screen (like on the iphone) rather a hardware keyboard that some people prefer.
The Samsung Galaxy S II is slightly bigger than the iPhone (by roughly an inch), so it has plenty of room for a well laid out digital touch screen keyboard.
Yes the Sony Ericsson xperia x10 does have many touch screen keyboards, wether the Android Keyboard, the Japanese Keyboard, the Chinese Keyboard, the Korean Keyboard, the Defaut Sony Ericsson Keyboard and downloadable keyboards such as the Iphone Keyboard.
simple you have a touch screen :D
