Android twitter integration for my contacts
I recently changed my phone from iphone to galaxy s2. Thus I had a problem importing my contacts. In the end I found a way by exporting it to google contacts from itunes and then importing it again from my s2. 

Now the problem is that, I need to know how this twitter integration works. I looked through my contact list on my phone and some of them have pictures attached to their names. I realise that the picture is being used from their twitter account. I follow these 2 people on twitter but how does android know that these people in my phone contact list are the people i follow on twitter? I need to know how that works. As i realise the person I am following on twitter and the person i have in my phone are two different people but somehow they are combined to one. Meaning the phone number that I had of the person belongs to someone of the same name.

Please help
