ServiceDesk and Blackberry Notifications

Prior to using ServiceDesk, we had a seperate Exchange mailbox/address (ex, helpdesk@it.com) for users' to send requests to. This mailbox has a Blackberry tied to it so that the oncall technician could see that there was a request made outside of normal operating hours. What we have been doing since we've purchased ServiceDesk is taken email requests sent to helpdesk@it.com and copying them over to ServiceDesk manually creating each ticket ourselves.

We would really like to start having customers create their own tickets from the self service portal but then we're missing out on the Blackberry notifications during off hours. The Blackberry also allowed us to email solutions to simple problems during off hours and get any additional info, if needed. Is there any way to tie the Blackberry to ServiceDesk to allow customers to create their own tickets but still reply from the Blackberry when necessary?

I hope I've explained this well enough. If there is any additional info that is needed, please let me know and I'll try to explain in further detail.
