OK, I found the app I've been looking for to send emails, and IM's as Sms...Sorta.
Here's an old version of the app:
xda-developers - View Single Post - The New Cab Collection [Updated 6/8/09]
I can't seem to find a newer version that that includes MSN, and supports Email. I've found a few links but all come up, Error. The version that was on my zn5 was: 2.8.3. I saw an app version 5.x that was taken from the HD2..but that one uses data to connect.
