The iPhone is a test platform to prove to yourself/investors that your products have merit and can sell. You can do without it but the iPhone means press which means users which means money. Android would be a good platform because of the App Market and so will Windows Mobile and Blackberry but it will be a lot easier on those platforms once a store comes to the OS.
There is a lot of room in the mobile space but my biggest fear is that instead of developing substantive companies, businesses pander on the spam/one-hit-wonder line. Don't be one of those companies, spend the time to develop an idea that has value and meaning.
