Can phones be rigged to explode like the pagers in Lebanon? Experts say it's possible — but unlikely

Men and women stand outside a coffee shop on a busy city street. They are all looking at their phones.

Given the deadly explosions of pagers owned by members of Hezbollah this week, many smartphone users are asking if their devices could also be remotely set to explode. While it's technically possible, experts say the level of technology and more rigorous security processes involved in phone manufacturing mean it's unlikely.
