Submission + - One month on the app store - not rich yet (blogspot.com)
For anyone planning to make a living from iPhone apps — take a look at the first couple of weeks of sales and make note of the fact that the app is selling for only $0.99. For those of you who like to dream of making it to the big time — take a look at the last few days of sales on the UK app store and imagine what it would like if that was happening in 50 countries!
If you don't want to read the artical, then here's the executive summary, first couple of weeks 0-10 sales a day, last couple of days 300-350 sales a day.
