iPhone App and back end like path.com

Looking for iphone photo app much like [login to view URL] and its backend web service. Different approach but same base functionality. Must be original code. Users will be able to create a profile to store more information. Looking for high quality design of user interface. Willing to split job to tender again if code is up to scratch but not design or vice versa. Supplier must be able to provide handover documentation and ongoing support and maintenance.
