I jailbroke my brothers 3gs not long ago and I had to use Cydia to download something called SAM Preferences or something. Google "iPhone 3GS stuck on Searching after jailbreak" and then you should see a tutorial which tells you to download SAM Preferences and set it up to work for your area and you will then get signal

Hope this helps

its your base band chip thats need replacement i can help you with that
