Hi! I have a very important question to ask you: Which smartphone is the least breakable! I'm going to buy one for my little sis and she has the bad habit of breaking or dropping her phone or letting it fall out of her back pocket and into the toilet.

Can you help me?

No smartphone is strong enough to bear humans' anger, if someone is willing to break it - they will. I will suggest you to have a smartphone that have fiber body and least Corning Gorrila Glass 2 protection.

I hear a lot of good things about gorilla glass, which I believe the Droid X series has?

Then try iPhone ....it wont break
