Hai, just updated to iOS 5.1.1 by creating a custom baseband using redsnow. so i put in my GEVEY sim card after and I am able to unlock the network and my network shows but after a few mins it shows "no service" and eventually "no simcard installed". i have tried it over and over again i have even jailbroken my phone already but i still cant get the network to stay on since the update. My baseband is preserved to 04.10.01
