Necessary for phone 3G to save SHSH?

[Croire]

Um...I'm not too sure where to post this question but I'll post it here anyway as a safe bet. Is it necessary now for a JB iPhone 3G running on a 3.1.2 fw to save the SHSH blob with Cydia? Or can I just restore using a 3.1.2 custom firmware? My iPhone is currently stuck at the apple logo and I would like to stay on the 3.1.2 fw. Any help would be great. Thank you in advance.

You can always restore to 3.1.x on a 3G without SHSHs.

You only need SHSHs for 4.0+. its too late to grab 4.0 and 4.0.1 anyway...

a custom 4.0 wouldn't require the shsh's either

Which one would be better and cleaner? Restore using a factory firmware from iclarified or using a custom firmware? Or will both do a good job. My iphone is unlock and jailbroken by blackra1n but it is running on the factory firmware not a custom firmware. By restoring my iphone with the 3.1.2 custom firmware, I will be staying on 3.1.2 FW right? My iphone will not update to the new 4.0.2 FW right...?

Doesn't matter both are fine assuming you create your own custom fw. I personally don't like using somebody else's custom fw but that's just me

shift+restore will prevent from upgrading to 4.0.2.

I didn't create my own custom firmware. I thought about using the activated firmware from this site.

Perhaps I should use the one from iclarified. Those are the factory firmwares right? Thank you in advance.

You can get stock fw from the downloads section here on MMi

Okay, hopefully nothing goes wrong. Thank you so much!
