If it is a 3Gs and Not a 3G...
Connect to iTunes on the computer you usually Sync with and “ Check for Updates “...
If an Update Appears Install it... if not... you are up to date for your particular Device...
See the Using iTunes Section Here...
How to update your iPhone, iPad, or iPod touch
However... if it is an iPhone 3G... it can Only update as far as iOS 4.2.1

Important that all of your data be on your computer BEFORE you attempt to update. The update is an erase/restore deal.
I did that, but now I cannot Active my phone. What should i do now ?
If your iPhone was unlocked unofficially, update has locked it again. Use SIM from original carrier.
Thanks so much, I will do that .
If it is AT&T, Read this. Online Unlock request link in the page
