iPhone 3GS problem

[highlander88]

I jail-broke a iPhone 3GS with greenpoison and it won't find my cellphone provider. Everything works but the network shows nothing with a new Sim card. What did I do wrong?

Have you installed ultrasn0w through cydia ? Did you install the iPad baseband ?

how do I install ipad baseband?

1) Open redsn0w

2) Select the firmware your iPhone is on

3) Let it load, once it loads check the "Install iPad Baseband"

4) Press next, follow the DFU mode instructions

5) once its all done it will reboot and then unlock via Ultrasn0w 1.2
