Hold down the Power Button at the back of the Mac on the side. (probably left)
The easiest way someone can find an instruction to install a home button is using Youtube. There are other websites like Ifixit which explain installing a home button on the iPhone 4.
You mean the 'Edit' button on Photos? You just have to be on iOS 5 up to get this button. It's a built in iOS feature. If you are not yet on iOS 5, you can update using iTunes.
If you can't hear on your iPhone without using the speaker option then check the mouth speaker at the mouth and see if it may be dirty.
No possible way
take the battery out then put it back in, then plug it in, if it doesnt turn on try taking the faceplate off
Using the "power" button will result in you being taken by to the main menu.
You can take video using iPhone 3G using Cycorder which is available for free, but to do so require that your jailbreak your iPhone 3G. You can also spend your money on the iPhone 3GS so that AT&T can laugh up your money and continue to provide horrible services.
No.
you just press the power button :)
