    Hi guys, I just want to ask if I can upgrade my iPhone 4 baseband 04.10.01 running 5.0.1 to 5.1.1 without losing the unlock? I understand that I can jailbreak it when I update (not through iTune official way), but I rely on Gevey sim to unlock, so I don't want to risk it. Really appreciate any help from you guys. Thank you.
    P/S. will using redsnow create custom firmware help? I already downloaded firmware for iPhone 4 (GSM) 5.1.1 from idownloadblog just in case I could.

    Yes. You just need to create the custom firmware.
