i need to develop an iphone app.
the app will allow users to sign into their account and create music playlists and share them with others.
i have already developed an online version (purely web-based), but I need to have a smooth version that works on the iphone accessing the same database.
please indicate in your bid time/costs. also if you have previously developed an iphone app, please let me know which one so i can review its design/functionality.
