Following post was actually meant to follow a previous post and is now redundant. But I will leave it in as it might contain useful information for other reader.
As Simon says, the level depends on the devices you are trying to build for. But later devices have more features making it easier to develop, so there is a cut off point where you need to decide whether the effort is going to matched to the reward.
To find out the OS level on a phone or Simulator, use Options --> About.
Have a look here for some stats that may help you decide:
I personally develop for OS 5.0 and above only, unless required otherwise.

As noted in my previous post. I personally would not develop for any OS before OS 5.0 unless I really have too.
But it might also depend on what facilities your app requires. For example, if you need to use NFC, then you are talking OS 7 only.
