I miss BBM, they still reign king when it comes to data-based instant messaging. It blows WhatsApp away. And I've had WhatsApp for 5 years now and never paid. I change my number pretty frequently, so that's probably why..
This is the only thing I dreaded about switching over to the Windows Phone platform... I knew BBM wasn't going to be released anytime soon for it

(but it will come). So I'm hoping it flops purely for that reason, so I'm not left out - but I know everyone in my area is going to be switching back to pins ASAP. I feel like everyone I knew had a Blackberry 4-5 years ago, we exchanged pins not phone numbers.
