8100 tweets/fb messages not appearing in messaging inbox

[DV26]

Hi everyone, I recently purchased a 8100 because I missed the blackberry experience but with past bb's all of my incoming messages e.g what's app, Facebook and twitter messages all used to show up in the messaging application. For sone reason I can't get any of these to show up in this application anymore. Only txt messages and bbm messages show up. I was wondering if this is normal for older blackberry's or whether there's a problem with mine. And help would be great. Thanks in advance!

Forgot to mention that I've checked the options in each application to show up in the messaging app but nothing seems to work. is that a problem with the 4.5.xxx firmware?
