take a look at
sms2mail
it is a small application i wrote and while i re-used the code in quite some applications my company decided to give it away for free.
sms2mail overrides your sms-receive-function in your BB, receives SMS and forwards them as an e-mail to a given adress.
per default the devices mail-adress is being used.
You get all received SMS directly to your mail-adress and thus into outlook (etc).
