iPhone Voice Recorder Utility

My iPhone broke. The screen just died a slow death, getting brighter and brighter and then very hot and then...nothing...over the course of a morning. With no phone to play with this morning, I did a lot of thinking and hunting through iPhone foundation files instead. And I seemed to find quite a lot of interesting calls in the Celestial framework, specifically the AVRecorder class.
I was pretty sure the capability was in there to begin with--after all, didn't the Steve promise us one back in the January Keynote? So that certainty made the class hunt go a little quicker.
When I returned home from the Apple Store Genius Bar with my new loaner, I put all that thought into code and this is what turned up: my newly written iPhone Voice Recorder utility. Yes, it is little more than a proof-of-concept but (a) it works, and (b) is the first step towards iPhone VOIP.
The recorder saves in Adaptive Multi-rate format (.amr files) that you can play back in QuickTime. I put them into the /tmp folder and tell you the name of the file when you finish your recording.
As always, I'd love to hear feedback and questions.
Update: Improved version with app wrapper is here

Great work on this - I'm actually VERY interested in getting the iPhone working as a recorder for rehearsals and the like - so 2 questions for you :
1. Can you change the sample rate? Can it be made stereo somehow?
2. Will any external microphone potentially work with this?
Again, great job!

Thanks for figuring this out, Erica. You rule!
Just wondering: is it possible to make a higher-quality voice recorder for the iPhone? Like something that records in a different format, or a higher quality version of amr? I did some test recordings, and this does make a great voice recorder. It would be fantastic, though, if you could use the iPhone as a general-purpose sound recorder.
AMR is designed specifically for the voice, and one voice at that - and it doesn't work well as a general recording format. I really wish Apple had just included general recording capabilities in the first place, as they have done with their iPods.
Erica, you said that recording phone calls with this application is possible. When do you intend to make that happen? Since i'm really looking forward to a way where i am able to record my phone calls. Thanks.

BTW you do indeed rock!
Erica,
I downloaded the app version and placed it in my app folders, I have the icon on the phone but when I choose it I only see a blank page. What am I doing wrong any idea?
hi!
I want to use my iphone for a voice recorder so that I can record the lecture at the class. Can I use your program for this purpose? And please let me know how to use it (I downloaded your vrecorder and tried to open it but it asked me which program I want to use to open this file)
I am not good at the current technology. If you explain me more detail, it will be highly useful for me. Thank you so so much!
