Thanks for all the suggestions. I am adding few more things that I forgot earlier - Stress Testing - ??? App Distribution - Zubhium App Marketing - AdMob, AppSurfer, AppBrain Also, is there some service that can provide initial validation of an idea. I need some service through which I can contact 20 users and ask them if they will use a particular app and if so how much will they pay for it and what features they would like?
