I know this is common knowledge for most of you but since I haven't used text messages on my cell phone before, I had a question. I'm planning on getting the new iPhone 3G with the 200 text messages plan. Wanted to know how text messages are charged. Is it every time you hit send? Is my 200 limit count by each word of text? When I receive text does that count? And is there a way to track how many text you've used in the month, so I won't go over? Thanks in advance!
