Absolutely, this is a wonderful forum to gain knowledge about your iPhone. As Hookbill said, there are opportunities for all of us to learn something new each day we are here!
So having said that...
Welcome to the Forum!! So glad that you joined us and hope that you gain a lot of good info here.
Remember that using the Search Function may help you find answers to many of your questions that others have asked before, but feel free to start a thread if you can't find what you are looking for.
This is the best iPhone forum on the planet, and I've tried several. I knew nothing about iPhone before coming here and the knowledge I've gained from these forums has helped me to write my own iOS web apps. This place ROCKS!
