iOS here as well as Android.
Both are a dead heat, but I like having battery life on my mobile...
Before getting these two, Android annoyed me with awful battery life and the iPhone was expensive.
I was BlackBerry by choice, I loved that thing more than anything else. It could do everything the others did, the best part? I felt like a true rebel. My Bold 9700 was slick and could punch out messages without annoying autocorrect. If you screwed up, it was your fault (despite the feature being available), voice commands, and one of the best sounding digital audio players out there.
It was just simply "uncool" to own one.
When I get my hands on a BlackBerry Z10, I'm back to my CrackBerry habit!!!
