Need opinions

I have a new iphone 4 that I got yesterday and I got lucky cause it has the 4.0.1 firmware on it. (Only thing is that there is no shsh files saved, I even tried to save shsh for 4.2.1 but tinyumbrella won't do it.) Anyways I want to Jailbreak and unlock it but want to try and preserve the baseband, it's at now 01.59.00. Should I upgrade to the new firmware 4.2.1 or just stay at 4.0.1 and JB with jailbreakme or limerain?

My question is what is is the best thing to do? Stay where I'm at on 4.0.1 or upgrade to newer firmware, if I decide to upgrade to new firmware how would I do so without updating the baseband? I know there is redsnow or pwnage tools but after researching the web I'm confused on how to or can't decide what one to use?

I would say stay at 4.0.1 because 4.2.1 is tethered and well untethered is just better.

use jailbreakme.

+1 on that

Yes, stay at 4.0.1, jailbreak and have cydia save your shsh for 4.2.1. Only thing is that if you need to restore, you will only be able to go to 4.2.1 as you won't be able to go back to 4.0.1

The good news, however, is that if you restore (and you will have to restore to no earlier than 4.2.1), you will be able to preserve your 01.59.00 baseband ad infinitum using either custom firmwares or TinyUmbrella's TSS server, so your unlock is safe.

I'm going to keep it at 4.0.1 but
which is better to use for custom firmware to preserve the baseband?
redsnow or pwnage tools?

for some reason too tinyumbrella won't let me save shsh for 4.2.1 and I don't know why?

redsnow doesnt preserve baseband. Pwnage tool is the way to go for that.
