I bought an iPhone 4 it came with 4.0.2 and it was too late to downgrade to 4.0.1 so I could jailbreak...the dev team blog is saying not to upgrade to 4.1, but that doesn't apply to me, correct? Since I'm not jailbroken now it shouldn't matter, right? Thanks for any help!
Got a tip for us?

You can save them. I did it last night from my wife's 3GS before upgrading to 4.1. However I can't confirm if you can actually restore using them.
If u save them u can obviously restore with them. But apple stops releasing them as soon as a new firmware version is out.
Don't upgrade if you ever want to unlock your phone, as 4.1 has a baseband update. If you don't care about unlocking (resale value etc) then upgrade away
on a related note, you can upgrade to 4.1 without upgrading your baseband.

I think you read it wrong.
Yes, you can upgrade your firmware without updating your baseband version.
No you cant downgrade your baseband once it has been updated.
Unless you want to sell it unlocked next June-July and be able to move it faster and for more money.
Am I reading this wrong? This quote is directly from his mainpage, near the bottom:
"I have heard a few folks voice concerns about how they can downgrade their 2.x baseband to 1.59.00 on iPhone4. Here are the basic steps:
Close TinyUmbrella (if open)
Close iTunes (if open)
Remove ALL lines in your hosts file that contain gs.apple.com
Windows: Start -> cmd -> ipconfig /flushdns
Mac: Terminal -> dscacheutil -flushcache
Start iTunes
Restore (NOT UPDATE) Stock 4.0.2 iPhone 4 - 4.0.2 Download
Note that this will only work while Apple is signing 4.0.2 SHSH requests. This is due to the way Apple now updates/restores Baseband Firmware for the iPhone 4 different from the way it did to prior devices. Lucky us..."
This seems to tell me that you can still downgrade baseband if you've already updated it...Right?

Oh I see.
Its a Yes and a No though.
As soon as Apple stops signing official 4.0.2 even with SHSH's saved you will not be able to downgrade the baseband.
Thats only for that small window between firmware releases that Apple still signs 4.0.2 for a day or 2 even though 4.1 is out.
