Using the following open source code of
http://zbar.sourceforge.net/iphone/index.html

Reproduce an existing C# .NET app that will create orders on an iphone by:

Selecting customers from a database on the phone
Scan barcodes (using source above) and compare to items in a database on the phone
Make calculations and various other functions

Send orders to a server (insert into existing tables).
Receive updates (inventory and customers) from the same server.
Data resides on an MS SQL database on a server and can be accessed via a web service application on IIS on that server or any other method you may suggest.

This application currently exists for windows mobile handheld devices and we want to
create a similar app for use on an iPhone. We will supply a working version of the existing app as well as all the tables. If you require a download of it for review on WM6.1 we can supply it.

Well documented code required
