Hey man.. Okay I tried running this application f0recast v.1.2, the app detected sum stuff as below
Jailbreakable : Only with SHSH blobs
Unlockable : No
Tethered : Depends on Jailbreak
Ok, so what does the above tells me... Infact today I just tried jailbreaking, i tried the below link "http://www.redmondpie.com/how-to-update-iphone-3gs-3g-baseband-to-06.15.00-with-redsn0w-0.9.6b5-for-ios-4.2.1-unlock/" but seems not working.
Okay..here are some info
IOS : 4.3.3
Modem Firmware : 05.16.02
Appreciate your help

tx in advance.
@Djveej
U still didn't answer my question on your phone unlock status i.e. official unlock from Maxis (since only Maxis have 3Gs), Singapore, Australia, NZ etc but US AT&T iPhones are locked. But from what I see:
1. Your iOS is 4.3.3 and you should use Redsn0w 0.9.6RC16 instead if your phone is officially unlock
2. If you phone is a locked set, then you are screwed since your baseband (modem firmware) is already 05.16.02. Ultrasn0w can only unlock up to 05.13.04
3. f0recast shows that unlockable status is NO so I assume yours is a locked set unless proven otherwise (I'm not familiar with f0recast)
So if your iPhone 3Gs is officially unlocked phone then I suggest you to restore back the phone with 4.3.3 then jailbreak with Redsn0w 0.9.6RC16 and you don't need Ultrasn0w.
If your iPhone 3Gs is a locked set then you end up with an iPod Touch instead because baseband (modem firmware) 05.16.02 is not unlockable as for now
So your first priority now is to check whether your phone is locked or unlocked set

What about the baseband thingy? I still don't understand till today

If your phone is an official unlock phone then you should not worry about baseband. People particular about baseband if their phone is a locked phone i.e. from US AT&T.
