One of the things I miss about BlackBerry 7 devices is the ability to change up the theme. With BlackBerry 10, I sometimes get bored with the look and wish I could change things up like on old devices. I have a bit of "wallpaper OCD" so instead of changing themes, I find myself constantly changing my wallpaper to keep things fresh — and it seems that I'm not alone.
When asked in our poll, over 60% of CrackBerry readers also miss having the option to theme on BlackBerry 10. There's also a small set (18%) that like things stock the way they are, and the other 18% that don't really care either way.
Sadly themes are one thing we'll most likely never see on BlackBerry 10. For a while it was believed that the option would be there at some point, but it looks like it's off the list for the time being. There are some options for pseudo-themes on BlackBerry 10 — making your device looked themed with just a wallpaper — but it's not quite the same.
