I am looking at my first iphone (3GS) but am worried about how delicate this thing will be? I have a bad habit of being rough on my cells phones, especially dropping them from time to time. Will the 3G stand up to a few dings here and there? I really do not want to buy a thick bulky case b/c I carry my phone in my pocket. I am thinking about the Speck Candy Shell to protect back and maybe just a screen skin protector for the front.
