Designed for the BlackBerry
For many users the availability of Pocket Informant on the BlackBerry platform is a major reason to use the BlackBerry and its because Pocket Informant is the best known and best selling PIM on Windows Mobile since 2000! But we didn't just come and port it to the BlackBerry and say we're done; instead we looked hard at what BlackBerry users wanted in a full featured PIM and how they used their devices. Pocket Informant for BlackBerry is the culmination of hundreds of users and thousands of man-hours of design, engineering, and leadership in the mobile PIM market. We are excited to finally bring this to you!
