Question from Derek: I had an app I really liked called 'fast camera'. It allowed a rapid stream of photographs to be taken. Once the switch to 3.0 occured it vanished. Do you know anything about this?

Answer: Hi Derek, I actually use FastCamera myself, and sadly this is one of many apps that currently no longer work under OS 3.0. I am not sure where this developer is with his discussions with Apple, but I suspect he is like many others, on a fast train to nowhere.

I have emailed Phil Schiller regarding this ongoing OS 3.0 compatibility issues and Apple's refusal to approve some apps (more on this in a later post).

Question from Luc Perard: Are there any iPhone holders that are designed just for photo&video usage of the iPhone? Trying to take a self-portrait is difficult with the iPhone: hard to press the shutter button while correctly holding the iPhone. Any suggestions would be appreciated.

Answer: Hi Luc, until the app approval issue is resolved and apps like FastCamera work under OS 3.0 you are a little limited to what you can use, however at present I would recommend using an app called FotoTimer [AppStore Link], which as its name suggests is a self-timer app for the iPhone with the Joby Gorillapod Go-Go tripod.

These are my answers, but if any of you have any alternative suggestions, then please post your comments.

I have had a number of questions from readers, so I have decided to make "Readers questions" a new feature of the site, so if you have any iPhoneography related questions, then email them to me and I will do my best to answer them.
