Cell Phone Based Project Management Software

I understand that it would be possible to run some of the newer web based project management software on an iPhone or equivalent type device, but we need a solution capable of running on our employees’ conventional BlackBerries if there is such a thing. In the past couple of years our entire method of collaborating and communicating within our organization has changed due to the BlackBerry and it would be wonderful if we could integrate Clarity Project Management Software into this wonderfully addictive new platform as well. If not we may have to scrape up the funds to upgrade our existing army of BlackBerries with the newer models which hopefully will feature a full web browser not unlike the iPhone.
