My current baseband is 03.10.01

If 03.10.01 is not unlockable, is there a way I can change to a baseband that is?

If I'm going to upgrade to 4.3.3 in order to JB using sn0wbreeze 2.7, is there a way to know what baseband is the upgrade going to install on my iPhone?

There are signed shsh files for each handset - each is unique - tinyumbrella saves these on your computer in a .shsh folder and on the cydia server. you can only use those specific to your device to go back. if you do not have the shsh for the ipsw version with the older and unlockable BB, then you are out of luck... 4.01 I believe is the last unlockable ipsw version with BB 1.29, I think - none after are unlockable for the iph4, period, end of story!
as mentioned, the gevey or rebel sim may be the only option but also comes with some risks, most due to the need to call 112 to activate it and upon every reboot... 112 is an older emergency number still used in many areas - I am in Norway now and it is currently in service here. I think in the US is get routed to 911.

Thanks a lot, best answer I've ever gotten.
In that case, I'll update my BB hoping an unlock comes out for the newer one

I have an iPhone 4 with baseband 1.59 running iOS 4.0. Am I safe to upgrade to 4.3.3 or will the upgrade change the baseband to one that will no longer support the unlock?

Gotcha. So I can do this, no problem. But is it safe? I have an AT&T iphone that I replace SIM card with one from Rogers for use in Canada. Need to know that there are no problems/unlock/jailbreak isn't buggy. I'm still on 4.0 now and the unlock works fine. Don't want to jeopardize anything. Thanks.
