Hi,
I can develop this app for BlackBerry 5.0-7.1 and BlackBerry 10. Please send me the requirement document. I can change my bid accordingly. You may like to look at my profile (https://www.freelancer.com.au/u/programmerWorker.html) to see more information about me, the projects I have developed, and the reviews I have received from the previous employers. I hope to hear from you soon.
Thanks,
