IPhone App Business Marketing Activities

Just started a mobile app business (iOS & Android) and I have decided to share my experience with everyone. Started working on the first app almost 3 months ago and I hope to submit the app in 2 weeks. Currently I am focusing on marketing activities. Here are some thoughts http://tukulogics.com/blog/ (Part 1 & 2). None of these are proven for me but I want to try all of them. Ideas are mostly compilation from reading 3 app marketing books and from online research. I would love to hear your feedback. So, let me know what you guys think
