We already knew that iPhone-Dev Team is today going to announce the much anticipated iPhone 3G / 3GS Baseband dowgrade feature. Now, the new Redns0w 0.9.14b1 version is available for download with a Baseband downgrade option for those running the standard iPad’s 06.15.00 Baseband on iPhone 3 / 3GS.
For those who don’t know, the baseband 06.15.00 was previously available for iPhone 3 /3GS as the only Ultrasn0w compatible baseband. But due to some problems like non-GPS functionality and inability to use stock IPSWs, the new Redsn0w 0.9.14b1 gives you the option to downgrade iPhone 3G / 3GS Baseband from 6.15.00 to 05.13.04 which is the most stable iOS Baseband currently present.
Tutorial to Downgrade iPhone 3 / 3GS Baseband (06.15.00 to 05.13.04) with Redsn0w 0.9.14b1:
