Right out of the box, iPhone is incredibly easy to use. If you want to get the most out of every feature, you've come to the right place. This video tutorial straight from Apple will teach you how to record voice memos on the Apple iPhone 3G. The iPhone redefines what a mobile phone can do.
Capture a thought, a memo, a meeting, or any audio recording with Voice Memos. When you're done, edit your recording, then email it or send it via MMS.
Record memos (or any audio):
Record ideas, reminders, meetings, class lectures, notes — any audio you want — using the built-in iPhone microphone, your headset, or an external mic accessory. Voice Memos records even when you're using your iPhone to do things like check email or surf the web.
You can trim recorded memos right on iPhone. That way, you only keep what you need most.
Keep all your memos organized by choosing labels from a predefined list or by creating your own custom labels.
Send memos to your friends and colleagues via email. Or attach them to an MMS message. Memos you record on iPhone sync back to your Mac or PC via iTunes, so you can share them later.
