I downloaded bbm on my iPhone but it won't let me add pins?

It's a free bbm app for iPhones but when I type pins in the message is not delivered and when the other person tries to find my pin it says it's invalid. Does iPhone bbm only work for other iPhones or does it also work for other blackberrys? How can I fix the problem?

IPhone 5s vs Nokia Lumia 925?

I'm looking to get a new phone, either the iPhone 5s or the Nokia Lumia 925. I mainly use my phone for texting, calls, and occasionally browsing the web. Extended battery life is a must, responsiveness to what I'm doing needs to fast, and camera use isn't a big deal. Which phone should I get?

P.S.- I'm probably going to get a Microsoft Surface RT tablet, so I guess that plays into the decision for the phone too.

How to free up some space on iPhone 4, 8 gigabytes?

So I've deleted all of my apps and so many pictures that I only have 350-400 pictures that mean a lot to me. But I need "at least 3.7 gigabytes to update to iOS 7" and it's at 3.1 gigabytes of free space. I just need that little bit more space! Is there a way to move all of my pictures on my iPod and then add them to my phone later?
