Is there any way to replace one of the standard apps that comes with the iPhone? I don't like the standard calculator but it just seems like a waste to add one that I like and have two calculator icons taking up precious Springboard space. It'd be best to replace it, although I suppose I could use Customize to hide the original calculator.

back up to your computer and delete the one you dont like.
i do this all the time,
just make sure you have all the files in the app folder

Use Customize to hide the stock application - I have HP15C as my calc.
