I have developed some app on the iphone sdk and tested it on the simulator.
Can anyone suggest me the way to transfer my app to iphone to test it?

When i try to connect iphone to system and transfer the app ,xcode prompts saying that "device not connected".However i can see it in itunes.

I have also added installer to my iphone which shows number of applications.
Is there any way of putting my app so that it gets installed through installer?

Please guide me with the process of trasnferring app into iphone.

The majority of the iPhone apps that are developed via the SDK will not run on 1.1.4 or earlier firmwares.

If you have one of the 1.2 firmware versions installed on your iPhone, you can copy them over to your iPhone via xcode.
