Downgrade iPad’s 06.15 baseband on the iPhone 3G or iPhone 3GS

[fijiman]

A quote from the devs:

"Typically you’d have the 06.15 baseband if you unlock with ultrasn0w but updated your iPhone baseband past 05.13.04. With this new capability, you can now downgrade specifically from 06.15 to 05.13.04 (even if you never had 05.13.04 on that device before). This gives you the best of both worlds: ultrasn0w compatibility and a normal iPhone baseband with full GPS and the ability to use stock IPSWs again."

Was never a big fan the the iPad baseband fix....a bit hit/miss.....

Thanks Dev Team. Getting fed up of having iPad Baseband on my 3gs. Hopefully I'll get to utilise this and get it done before I go away in 2 weeks!

This does work, I tried it on my 3Gs running 5.1.1 last night and I admit it did take a couple of tries but it works if you do persist, and now I can upgrade to iOS firmwares without having to worry about the iPad Baseband. Now all I have to do is put the Jailbreak back on!
