These two cases are very different. In one case the police have a suspect in custody and strong evidence that they were engaged in illegal arms dealing, and are looking for specific additional evidence. In the other, the police are basically going on a hunch, with suspects not in custody, and seeking to search the phones of a broad group of people for a broad array of evidence that they don't have good reason to believe exists. It's not as simple as "Can search phone? YES or NO" if the cops were asking to search filing cabinets, the rulings would be the same.
