iphone utility application tutorial

I'm very new to iPhone development. I want to create a utility application much like the weather app (enter zip codes for cities to track the weather). The weather app allows users to scroll through their favorite places. There's a flip side where you can manage your selections. I am looking for a tutorial on how to create a similar type app. Can anyone point me to a good tutorial for utility iphone apps please? I've been googling and can't find what I'm looking for. Thanks in advance.
How about this? I found it by googling "iphone utility application tutorial". You should do that next time. :)

iPhone - where can i find a sample of GKVoiceChatClient?

I want to be able to let users of my iPhone app communicate using the GKVoiceChatClient classes. The documentation for the 3.0 SDK is very vague and I don't see any good samples in the Sample Code either.
Can someone please tell me where I can find some working example of in-game voice using which I can learn how to use it!
Thanks.
You'll need an account on the Apple Developer forums, but I stumbled across this a little while ago. I don't know if its functional but comments further along in the thread lead me to believe it is.

iPhone Accessory API

Can anyone give me a short version of what it takes to develop an app which connects to an accessory? I signed up to the 'made for ipod' program and got a huge pile of technical specifications docs which I have no idea how to start with.
Any help would be appreciated.

Reading the accessory section in Apple's iPhone app programming guide is probably a great place to start, and includes links to other, more formidable, documentation.
