Hi, got my friend an iPhone 4 Verizone (he always wanted one) but I know for sure he will not take care of it well. I can see him dropping it, scratching it with his keys (he'll probably put the phone and keys in same pocket), slip out of his hands, maybe spilling drops of liquid on it, etc...so I'd like to buy a durable case for him I really like what the Otterbox defender case offers, but I am wondering how much heavier/bulkier does it make the phone. Does it the Defender case make it impossible to comfortably fit in your jean/pants pocket or is it not really noticeable. Also any other suggestions? Basically I'm looking for a similar type case to Defender...one thing I think is useful for my friend is that the Defender case has like a hard screen protector and not one of those self adhering ones.
