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 ?

Thanks alot for help

Someone have the same problem after jailbreak 3GS.
The sim card seems blocked by your .carrier
The person order a new sim card to activate iPhone.
You could refer to it that i just found on internet.

But I think you could try to recover your 3G iPhone to the status before you jailbreak.
Refresh the os, maybe it could turn back to the factory configurations and the sim card could be recognized.

There's the instruction for jailbreak, you could try it after you recover your 3G iPhone.
