well on all my iphones i have had all otterbox. i prefer the Commuter Series cases because they offer great protection, and also have covers for the charging port and headphone port. when i was in the 3g and 3gs phase, i got a otterbox defender case. i liked it until i had to put it in my pocket, way to bulky, but it offers the most protection. i say go with the commuter and if you wanna be a lil cheap get the impact series, which offers more coverage than the other cases, for example it covers everything on the front side expect for the screen. btw they send out screen protectors with their products.
