Your opinion? Android Razrrm vs Iphone 4?

My family is all eligible for upgrades so we're all getting smartphones. Since the IPhone 4 is free now, it's either that, or pay a little bit of money for an android. My brother got the IPhone for his birthday, my dad got the Razr M, and my mom is picking out another android. I'm just torn between which is better. The Razrrm or Iphone 4 (since it's an older IPhone make)? I realize I would have to pay some money for the Android but it would be a birthday present or I would just pay if I wanted it a lot more. The main thing I'm concerned about is that I hear Iphones break easily and this Razrrm doesn't. Any other pros/cons for each?

Added (1). I'm a college junior so I don't really care about being trendy, I just want a good and sturdy phone.

Go for the RAZRRm it's twice as powerful has 40% more screen space without being massive phone, the speech to text is a million times better, it will soon have Android 4.1 which has an assistant like Siri but is exponentially more advanced just watch the YouTube videos comparing Google Now and Siri. Plus you get near field communication so you can share pictures, links, and more just by bumping the back of phones.

The iPhone 4 is so outdated now I wouldn't even take on for $100, not to mention being bland boring. If you want to be a "cool kid" and fit in with the "crowd" get an iPhone if you want a bad *** phone that rocks get an Android device.

4 is free with a 2 year contract and obviously not as good but still a really good phone. It wasn't that long ago it was a $600 phone.
