Social Network for BlackBerry

Hi to all, with my friend, I have designed and are building a social for Blackberry ... The project stems from two basic ideas:

1) Now I am in Warsaw from Italy and wanted to know what were the best players / best rates for my BB but there is no national forum in addition to an international meeting point; 2) Using the messaging system through the PIN you can create a communication system usable and beautiful, we wanted to meet girls with BlackBerry: D

You think we should focus on what aspect, what we should implement as soon as possible? May I hope to release the first beta on calls, and a public beta in June
