i am confussed

i am trying to develop a system for PocketPC

The idea is that we have a full SQL Database that we have a lot of info on

We want to give reps PocketPCs

There will be a number of different clients who want this system with different requirements

I am using the Northwind.sdf database for the data

I have created a programme that runs on the PocketPC and pocketPC Emulator using the data from this database
I can Update, Select, Delete and Insert data on the PocketPC (Clever me!!!!) and this data is saved on the PocketPC

So my questions are
1. How do I update the tables in an SDF database (The Northwind.sdf in VS2005 has its Identity Column set to False and it should be True)

2. Once ive updated the tables on the PocketPC how do i get the data back onto the laptop's database

Thanks
