Does anyone know of an app for the iPhone that can analyze sounds and tell us what pitch the sound is?
For example, if i had that app running and i go to the piano and play some notes, it should be able to tell me what notes they are.
IPhone – n app for the iPhone 4 that tells the pitch of a note through an audio input

Cydia's App Stat does exactly what you've requested. As far as I can tell, it exists since April 1st:
New Tweak in Cydia, App Stat, shows you your app usage statistics, frequecy of use, use of time and recent use. Supports IPhone, IPod Touch, IPad running IOS 3.2 or later. Free on Cydia Search for it.
Yes - the good splitters mix the pins correctly to provide mono microphone and stereo output in the same jack. You can of course get breakout boxes like the Griffin iMic and have the benefit of a cleaner D/A circuit at the expense of carrying another device that's plugged into USB. Just like everything - some of the expensive products are over priced and some of the cheap ones are worthless. I'd go with a name brand - especially if their products are carried on the Apple Online or stocked in the retail stores.
Lion does add a control where you can select the speaker icon in the menu and switch from input and output.
As to the rationale - unless an engineer from Apple steps up, we'll have to speculate.
Here are the reasons to have fewer ports. (They're not al good, but they are reasons)
- Simplicity - the iPhone / iPad / iPod touch all have one port. Many people don't need or want the confusion of knowing which port they plugged in to their mac. Just as you really appreciate having two, many appreciate having only one stereo jack.
- Internal simplicity - one less switch, one less moving part, several solder points.
- Internal spacing is far more important than external space. If you look at iFixit's excellent take apart manual - you will see there actually isn't room on the logic board for another connector. The design would have to sacrifice an USB port or the SD card slot to make room for a second package without reducing the space for the battery. These macs are packed incredibly tightly and despite the clean appearance of excess external space, inside they are packed like proverbial sardines in a can.
This lack of space likely cuts features from the smaller macs like a redundant mini headphone port.

Garageband can do this. Open a new (or existing) project and add a new "real" track with no effects. On the bottom edge of the window you´ll see a LCD-like window which usually displays the current time or measure in the track; depending on which version of Garageband you´re using, you can now either use the up-/down-arrows to switch to the tuner (tuning fork symbol) or click on the tuning fork symbol directly to select the tuner. Every sound that is picked up by your Mac´s microphone will now be displayed as note (with off-pitch)
