I accidently upgraded to 1.1.3 last night, and downgraded back to 1.0.2, then 1.1.1, downloaded sendowski files and so on to 1.1.2 s/w unlock. iWorld - Ireland selected, also completed: http://www.hackint0sh.org/forum/showthread.php?t=21769 , which is the work around for appsupport.framework. Still however I can't find a network (GSM) i go to carrier, there are no reception bars, it doesnt say "No Service" like others.When I go to settings-> Carrier, it shows "Loading" for about 2 minutes and closes back to settings menu. Now its displaying "error", Anyway as I said, I've followed everything to this s/w unlock and worked with iWorld and so on, really wrecking my head [vodafone btw] I dont have a stealth sim or anything like that, this is pure s/w unlock.

If you update to 113, after the SW Unlock (GEOHOT) you should use bricktool, reed this Post....

i havent updated to 1.1.3 after, I did it before and then downgraded all the way, im at 1.1.2 with s/w unlocked, I just cant get any carrier

thats the real deal, if you previously update to 1.1.3 by mistake, then downgrade to 1.1.2, you should use bricktool

Read the entire Post, it works for me
