[1.1.2(1.0.2OTB) ][Problem] iPhone crashing 5 months after unlock
I unlocked an iPhone for my friend in Germany back in December of '07 and here lately he says it's been crashing at random, displaying the Apple logo and such.
I used a 1.0.2 iPhone from back in September that had previously been used "legitimately" on the AT&T network here in the US and I can't remember exactly but I believe I used touchfree to jailbreak and then Anysim 1.1 to unlock for firmware 1.1.1 then used Oktoprep and the anysim "1.2.1u" or something like that to upgrade and unlock to 1.1.2.
He's coming to visit me in June and I told him I could take a look at it then. Is there any way to fix him up to 1.1.4 firmware using iLiberty or something like that?
Any ideas what's going on with my poor friend's phone? All help appreciated.
