Do not update your iPhone to OS 3.1 via iTunes
As DevTeam expressed, Apple's work on disabling jailbreaking taking effect. With the new (just bs release imo) release you may lose your jailbreaking and sim unlock "privileges" if you update your phone directly via iTunes using official Apple firmware. This rule includes 3G phones, you are advised to use custom firmware's made by pwnage tool. Pwnage tool works on mac as u know, there is no official windows version. They will release when they have time. As with 3GS and other new gen IPOD Touhes, you are advised to be patient and wait if you want to jailbreak your phone in near future or use another sim card. Of course SIM rules does not apply to SIM FREE iphones.

How to Jailbreak and Unlock Iphone OS 3.0.1 – SMS Virus Patch
You know the previous post, by the way they been warned a month ago not 6 days. Google (Android) and Microsoft (Windows Mobile) phones were affected as well but they patched this very quickly after the exploit warning. Well finally Appletards released the 3.0.1 patch early after their phone hijacked and crashed like live on tv news 
What you need to do for Jailbreaking Iphone OS 3.0.1 is:
- Have a copy of 3.0 firmware downloaded on your pc for your device (I bet you do already because of 3.0 jailbreak)
- Connect your jailbroken device iTunes and update to 3.0.1
- Launch Redsn0w and choose the 3.0 firmware for jailbreak instead of 3.0.1
- Follow the Redsn0w steps normally.
Well it works because nothing changed from OS 3.0 except the SMS patch, but can cause trouble in the future so I suggest you guys should (and that is what I am going to do) wait for an official Redsn0w release for 3.0.1 from dev team or an announcement at least to go on. Although they say no difference in the OS (Yeah we need to download whole OS just to fix something, how lame is that!) I don't trust them because Appletards wants to make jailbreaking illegal and impossible with 3.x firmware releases. and Dev Team announced the same thing adding that you can Jailbreak with this method safely.
Unlocking Iphone is still same steps I described and via ultrasn0w. Works with 3GS also.

How to Unlock Iphone 3G with ultrasn0w
Dev Team did it again and released the ultrasn0w today finally. Here is simple steps to unlock your iphone and use with any sim card freely.
- Ensure you have upgraded to iPhone OS 3.0
- Jailbreak your iPhone 3G using redsn0w or PwnageTool (this will also install Cydia/Icy)
- Run Cydia or Icy
- Please add the repo repo666.ultrasn0w.com to Cydia or Icy. That last “o” is actually the number zero “0”! If you use the letter “o” you’ll get an error.
- Search for ‘ultrasn0w’ in cydia or icy and install ultrasn0w
- Reboot your iPhone 3G
- T-Mobile USA users should disable 3G before using ultrasn0w
- Enjoy
