Being an iPhone developer can make you earn hundreds or even thousands of dollars daily.  Just like this iPhone developer doing and with her stats shown that is getting close to $2000 daily with his crossword application 2 Cross.

If you are inclined on developing an application then it is good to start to develop such application. Though there are already lots of application on the AppStore, there is still a chance that your application be rewarded counting millions of users of Apple products.

One nice rundown apple application blog that I regularly visit the AppleiPhoneApp blog, have some regular review post of application in the AppStore via a different sources.
