Hi, my iphone fell and the screen stopped working (can receive calls, but you can't see anything because of the broken screen). Anyway, i'm planning on taking it to apple to get a replacement by paying £120.

Vera bradley carry it all? Will it fit and iphone 5?

I'm looking for a good wristlet and I don't like the leather/ "hard" sided wristlets like from michael kors. I really like the one from VB - carry it all. However, I have an iphone 5 with a case that is similar to an otter box (commuter) so will it fit?

Am I better off getting the smart phone wristlet? It doesn't have that many slots for cards so that's why I'm a bit wary. And I don't like folding my bills up - but I normally don't carry a lot of cash anyway
