I am new to the iPhone but am starting to like a lot of them but not all of them include the icons I would like to be using. If anyone could offer some incite into where I can pull the icons off the phone to edit and also if there is a special naming convention needed with the theme. Maybe someone already did some of these edits and would be saving me some time... I am using the mobilepod springnav theme and am looking to change the text link to being my sms'ing app (bitesms) also looking for a dock icon for a twitter app and for a facebook app.

Thanks! any help on making these would be great and I will post them as soon as I have done some editing if others are interested
