How to down grade firmware to earlier version?
I just think if Apple updated firmware, which might render the GeoHot method invalid.
Do we have a way to down grade firmware as least back to current situation. still enjoy the unlocked iPhone.
For me, I lost WiFi and can not get it back. Maybe I have to try 1.0 firmware to do the HW unlock. see how it goes.
1.0.2 to 1.0.1 OK, to 1.0 FAIL
From 1.0.2 to 1.0.1 has no problem
Neither from 1.0.2 nor 1.0.1 can down grade to 1.0 firmware
Maybe it is not down gradable between the different Modem firmware
That's my result here.
