Hey folks we have told you before in our post that the baseband 6.15.00 on which the users updated in order to unlock their iDevices will be Downgraded which was confirmed by Dev team member @Musclenerd. now a moments ago he tweeted that:
@MuscleNerd: when is ur bb downgrade comin out for 6.15.00
@Fammbizz: TBH (to be honest), that won’t be looked into until after i4 unlock
Seems to be great news for all of us who are on new basebands 6.15.00. The reason behind it is that many peoples are facing problems with their 3G and G.P.S. So this downgrade will fix the issues people are facing. The basebands will be downgraded to one on which Ultrasn0w current version will work.
