First of all, I updated my iphone 3g from 3.1.3 to 4.2.1 to jailbreak it after.
Both my Iphones dont have the original sim card so I have to activate it in order to be able to use it and unlock it to be able to call etc etc.
So when I updated my iphone 3g I got stuck in insert valid sim card screen and now im fucked because I dont know how to hacktivate my phone.
The tittle says iphone 3gs this is because before messing up my iphone 3gs I wanted to try it on the 3g to see what was going to happen, now I see that it wouldnt have worked
now that I have informed abit of my situation I ask:
How can I fix my 3g, so I can use it again ?
How can I update my 3gs to version 4.0.1 ( so I can use jailbreakme.com to jailbreak I think its easier ) without getting unknown errors like 3194, or just how can I update my iphone and not end up in the enter valid sim card screen, to then jailbreak ?
