what do you mean by "restored it using iTunes using Redsn0w" did you restored using a CFW created by redsn0w? and are you on 5.0.1?

What baseband are you on? You can find that out by going to Settings --> General --> About --> Modem Firmware.

Also, what carrier are you on? Did you buy the phone from that carrier?

basically, im based in the uk. its a friends iphone which he wanted me to get working for him, he also gave me an att sim i dont know why because as you already no that network doesnt exsist here. it wouldnt turn on so i restored it using itunes, once it was on it wanted to be activated and i dont know what network its on so i used snowbreeze to hacktivate it. now thats done its now jailbroken aswel. the baseband is 06.15.00 the iccid says no sim. carried says not availible. im not too exprienced with iphones, but on my iphone 4 when i take the sim out it usually says no sim, whereas on on this iphone 3gs its not recognising the sim at all?

Suffix b in model means its a UK sourced. Contact apple and ask where it is carrier locked to, then contact carrier and request for official unlocking.

thanks i was trying to find out if its from the uk or not, i am uk based.

Since it's already on 6.15, just install ultrasn0w from cydia as @iH8sn0w advised. I was hoping you can save your gps by going the official unlock route if you didn't have 6.15 baseband yet.

I am having the same problem with my iPhone 3GS. It is from AT&T. I am in India with no AT&T chip, but a Vodafone Prepaid without data plan. First, I used redsn0w 0.9.9b6 on IOS 4.3.3, as I did not know what version I had. It connected to iTunes. It detected a carrier with only 1 bar of cellular signal. I was unable to make/receive calls or messages. I upgraded the phone to IOS 5.0.1. It kept giving me a Unrecognizable Build error on Jailbreak. I read the FAQ and then used redsn0w 0.9.10b3, and had to manually specify the IPSW, which got the phone to Jailbreak correctly, restoring the previous backup from iTunes as well. WiFi works, but now there is a No Service message.

Version: 5.0.1 (9A405)

Carrier: Not Available (says cannot get carrier list when I try manually)

Model #: MB717LL (A1303 on rear)

S/N: 87005F253NR

ICCID: 8991 2000 1276 6482 454

Modem Firmware: 05.16.05

Any help in this direction would be great!

Thanks ... Sunny

Looking above it looks abit unclear. Basically the iphone used to work on o2 before an update. Now it doesnt, when switched on it says searching for about 15 miniutes and then says no service. It is a iphone 3gs os 5.0.1 baseband 06.15.01 It would not activate when restored so i used snowbreeze to hactivate it.

What can i do to make it work?
