Samsung Moment

I am an avid fan of the Samsung brand. However on the original Instinct, which is my current phone, I very much dislike that it automatically begins deleting the oldest text conversations as it gets a certain amount of text messages stored. Does anyone know if the Moment phone does the same thing??

Also, I always cringed at trying to take discreet pictures and hearing a loud CLICK of the camera. (Being at a play for example, trying to be quiet.. and CLICK CLICK when you take a picture). Does this phone have an option to not hear that loud click when you snap a photo?

Thanks!
