iPlayer quickstart icon missing

I bought my Playbook (UK, 16GB) brand new in August/September and I remember clearing out a few icons, but not the iPlayer icon. In fact, I could swear I never had it on my device at all. I was in Carphone Warehouse the other day looking at tablets with my girlfriend and saw that the working display had a quick start icon. I have the site bookmarked, but I'd have liked the option of having the icon in my All tray. Any ideas how I can re-download it? It doesn't appear in my purchase history on Appworld, like the other native apps do. Thanks.

I've noticed it dissapear on mine as well, would be nice to get it back!
