I'm joining my wife's Cingular plan and need to get a new phone. The IPhone looks very cool but I have concerns about it running on the slower GSM network and the durability of the case. The Samsung BlackJack looks pretty slick and I wouldn't get harassed around campus for packing an IPhone. Here is a pretty good blog post about it.

Anyone tried the phone?
