Whats the difference between an apple Iphone 4g and 4s?

[MeghanMarie:]]

So im getting an Apple Iphone 4G and i want to buy a cover for it on amazon. And i was wondering if it mattered? Could i buy a case that says 4s for my 4g? Or does it have to be for a 4G.. Not very smart when it comes to electronics ahah Also if anyone knows of a cute pink leopard print case off of amazon for my phone you should send me the link! Thanks
