Thanks for the replies. I wish I was able to customize the profiles like on my BB. I like the phone to ring, and my texts to make a noise, but email silent. Can't really do that. But, it will never out weigh all the "pros" of the iPhone!
You can do this, but you have to jailbreak. I just jailbroke mine with greenpoison rc5 for 4.2.1 and works great. No problems at all. I did a little file transfer to change the sentmessage.caf file and presto.......no swoosh sound when sending text.
Yeah, did so the first day lol.
