Depending on the day I can get anywhere from 20-50+ SMS messages. I probably average less than 1 MMS a day, but it varies. As for email... I used to get a lot more, but I am in career limbo (still working, but, well... its just strange) at the moment and with only having my personal email coming through, I get maybe 10-20, depending on the day.
i get about 30-50 sms
about 8 emails not including spam
and i cant count the bbms...cuz i constantly change my status and i sometimes forget to take it off of unvailable lol
Email: 100 to 200 depending on the day
SMS: 50 to 100 depending on the day
BBM: 75 to 150 depending on the day (but usually that contained within about 25 conversations)
Phone calls: 25 to 50 depending on the day
Windows Live/MSN Messages: 10 or so conversations a day
How much of that is personal? About 20% .. the rest is work related... AND that is with as many filters and rules in place as possible to ensure that only things that are supposed to hit my Blackberry actually do... LOL
Then again.. look at my avatar and you'll get a hint of what I do for a living.. and hence the amount of communication that is occurring LOL
