Lotus Connections 2.5 Mobile
Did you try out Connections 2.5 on the Greenhouse yet? Did you find the mobile browser interface? It really isn't that hard! http://greenhouse.lotus.com/mobile
Mobile browser access will be supported on iPhone, iPod Touch, and Nokia S60 devices. We're rolling out only a few of the services and devices to start, but see this as a growing interface, as the rest of Lotus does. I know you will get instant value in being able to pull up a Connections Profile, update your status, and blog from wherever.
If your looking for RIM's BlackBerry Client for Lotus Connections, let them know it.
