"No service" error iPad BB update

[born2njoy]

Hello Experts...

Need your help...
I had to unlock my 3Gs 4.3 running in 5.16.01 BB.
As suggested in Jaxov.com, I used Jailbreakme 3.0 to jailbreak the device in 4.3 version and used redsn0w_win_0.9.9b8 to install the ipad BB (I had unchecked Install Cydia option while updating the BB).
The phone has 6.15.00 BB now, but it still displays "No service' after installing ultrasn0w. I tried re-inserting the sim card, erasing Network settings, reinstalling ultrasn0w without any luck.
What are my options now ?. Do I have to reinstall the iPad BB ? Please advise.

I have noticed that it can take a while before i receive signal after installing ultrasn0w sometimes around 5 minutes before it registers.

You should try resinstalling a custom firmware,then try again to unlock, be carefull to hactivate if you do not have a supported sim.If not flash the ipad baseband again

My iPhone 4 baseband 01.59.00 does the same thing. Usually a few reboots will fix it, either that or waiting a few hours for it to fix itself.
