Hey the thing is this can be confusing and that's why I asked right in the beginning of the tutorial to not get confused. Maybe I could have written it better.

We are all used to Nokia in India so the number display thing is something that is new to us. In iPhone, dial a US number, it will be like this '+1 605 8289-1234' with spaces and dashes at appropriate places. In Nokia it will be '+160582891234' without the formatting. Its not a big deal but makes a difference. Since iPhone is not supported for India the India format is not there. Tim has modified AppSupport to include some bit of it for India, I just added a few strings to make it more accurate.

So whenever you dial or receive a call, the number will display in this format with spaces. so if you receive a call from a landline instead of '+912223456789' it will display as '+91 22 23456789'. For cell it will be '+91 9812345678'.

In US iPhone if you receive a call you get the location info, it it will show the name of the place you are dialing or from where you are receiving a call. Again this is not there in India and the AppSupport guy has modified AppSupport with the capability but it is not installed by default.

That's where the callinfo.db and the callinfo_India sql file come in. The callinfo_India.sql file is a database of all India STD codes and mobile operator numbers. Just place the callinfo.db file in the mentioned folder and voila, you will start getting location and mobile operator info for calls coming in to iPhone or going out. But this only works for numbers that are not in your contacts.

Rahul PM me if you are still confused and I will put up a couple of screenshots.

To actually move files to your iPhone you need to install Winscp and connect via wifi to the iPhone filesystem. Winscp is like windows explorer over wifi that allows you to browse your iPhone's filesystem. Here's a useful guide:
