[1.1.1] I would like to upgrade to 1.1.4
I have currently got my iPhone running version 1.1.1 and I would like to upgrade.
I have probably used the newer method of AnySIM that didn't impair the baseband. What method shall I use to upgrade to 1.1.4? I have read a lot of discussions about ZiPhone. Would it work in my case?
I want to update, because my phone is sometimes losing the reception and shows "Network Lost" prompt on the screen.
With the best regards,
