I have a small doubt, so apologies first. I am creating an iPhone application using my Macbook. I want to upload it into AppStore after some days by creating a developer certificate and use provisioning profile. My friend wants to create his own iPhone application and wants to upload to AppStore for him personally, but he wants to use my same Macbook, but he may create his own dev certificate etc. I hope this is possible. Can we both use a same Macbook to develop different business(myself and my friend's) applications? I'm just curious to ask this doubt. One more question, Can we submit an iPhone application into AppStore without having own website page? Is it mandatory to have my own web site page for uploading an application into AppStore?
For first question: Sure, it is possible! Its all a matter of creating different Certificate and Provisioning and When you build the project making sure you use the correct certificate to Code Sign!
Second Question: You don't need a website of your own. I've come across many developers who uses their Blogspot address! But if you are serious and look serious, get a domain and a simple site :)
Cheers
