WRONG:

IF I WAS/IF I WERE

The subjunctive mood, always weak in English, has been dwindling away for centuries until it has almost vanished. According to traditional thought, statements about the conditional future such as "If I were a carpenter . . ." require the subjunctive "were;" but "was" is certainly much more common. A quick check of the Web shows "if I was" to be used approximately one hundred times more often than "if I were." Still, if you want to impress those in the know with your usage, use "were."
