The official call for entries for the second annual BlackBerry Developers Challenge is underway, with total prizes of $250 000.00 available from the Blackberry Partners Fund for winning entries.

Any new BlackBerry applications submitted to BlackBerry App World between 1 June and 25 September may be eligible to compete in this year’s challenge.
A total of 16 finalists will be selected from eligible applications submitted over the contest period. The finalists will each receive a prize package valued at more than $5 000.00 and be invited to compete for a grand prize package valued at over $100 000.00; and a runner-up prize package worth more than $25 000.00.
Judges will be looking for the most compelling product or service, clearly defined value proposition, and technical execution.
Four finalists will be selected and announced at the end of each month during the four-month challenge. User reviews of applications and download activity will be taken into consideration when finalists are selected.
All 16 finalists must present and demo their application to a panel of judges during the “BlackBerry Sweet 16” event, which takes place at the BlackBerry Developers Conference in San Francisco in November.
