(Downgrading to an earlier baseband that is unlockable with ultrasnow) The downgrading was developed for people that used the ipad baseband on their 3gs's and lost thier gps's.(ipads dont have gps but neither does the 3g so the downgrade is really pointless but your choice.... This is a gerenalized method...use google for better instructions I see you said 5.15.04. This is the basband for 4.2.1 so you dont need to do the step...

are you sure that a 3G doesn't have gps?

I would downgrade to 05.13 from 06.15, because the battery won't drain fast as **** on 05.13. also the wifi signal is much better on 05.13.

do you have the original sim in place or are you using the phone in a new country with a new sim? the SAM pref trick is blocked, so google before you start the jb and unlock...

good luck
