With the built-in MMS, you can record a voice memo.

Can you store this on your device? or do you have to send it?

Thing is, I find MMS voice attachments to be the perfect combination of file size & quality. For this, smaller is better

I just can't get any other programs (mVoice, PAR, Sound Rec) to create files that small which can be emailed. Either my setting combination is off, or the native just has it perfect.
