Does iOS 3.1.2 to 4.0.2 Upgrade need Original Sim to Activate [Q]

I have a factory unlocked iPhone 3GS (model MC132ZA, I used an Airtel sim card to initially activate my phone in India, now I am using a different sim card in a different country. Do I need my old sim card to activate my iPhone once again after I upgrade to 4.0.2.

Many Thanks !
