I know this is a rehash post to some extent but as I look at older threads I am still unclear on my type of upgrade.

I have a 1st gen iphone.
I want to update it to 2.x.

My Operating System 1.1.3
My Modem Firmware: 04.02.13_G
My Bootloader: 4.6_M3S2
My Current phone is activated and jailbroke
On AT&T but not on iPhone service

Can I use Winpwn 2.5 to update this phone directly to 2.x.x and if so are there any pitfalls or settings I should use or avoid?

If 2.5 is a bad choice, what should I use to update the phone?

Thanks for your help!

Just so I am clear....I can restore my phone to 2.2 then use quickpwn?

All I want to do is bypass activation. Not so interested in jailbreaking.

What I dont want is a bricked phone.

Thanks

Yes, you can do only that

Others have said in other posts that Quickpwn is not the right choice.

Have you actually gone from 1.1.3 using this product?

yes...same here. from 1.1.1 via quickpwn to 2.2.. works like a dream... Now if only I could re-find the way to get the text underneath all the springboard buttons out....grrrr

Things work quite a lot different on 2.x than on 1.1.1. You could install WinterBoard and select some of the themes that come with it: "No Docked Icon Labels" and "No Undocked Icon Labels".

Installing Cydia programs on a phone that has no internet connection: read this.

Editing binary .plist, .strings, .nib and .xib files:
* on your computer: Windows tool / conversion website.
* on your iPhone: convert those files in a terminal with plutil (installed with Erica Utilities) or edit them with iFile (Cydia links).

@Jim, agree...but must say am impressed with the leap in technology hahahaha....and thanks yes Winterboard did the trick, much appreciated!!
