I'm using a 4.0 3G and looking to upgrade to 4.1 to get some life
back in the slow iPhone :(
Dev team released redsn0w but no Pwnagetool yet for 4.1.
I've read about MSFT.GUY's release of custom bundle but is it safe to use it?
someone tried it ?
I absolutely need to keep the baseband from being upgrade and use ultrasn0w to unlock and can't afford to brick my phone
Any help is appreciated
