I not do think this is an option that can be done. Remember this is a different device and MFG. THere maybe a third party application, but you will need to research this.
The only way to do that is to purchase the application SMS Scheduler. You can save your draft and schedule to the certain date and time you want your text to be sent. However, from my experience, it's not very accurate. It sent some of my text messages too early..
I know this is an old thread, but in case someone finds this thread from Google:
I found a free app (for the rest of this year) called TXTLater, which will let you delay sending text messages with your blackberry. it can even do calls and e-mails too.
