another 3gs with 3.1.3 post

[surf_rider85]

Alright, I will try to keep this short. I have been up all night researching the in's and out's of this 3gs jailbreaking. I am still left with questions. I got an iPhone from a friend, never had anything done to it, very original form. Anyways, the stats are as follows...

3GS 3.1.3(7E18)
ATT
model: MC136LL
new-rom
modem: 05.12.01

It looked as though Spirit was my only option, but I was reading that it can be limited as compared to the others when upgrading later on, due to the type of exploit.

Do I have any option at this point? ATT is my provider now, so unlocking isn't a necessity, although I wouldn't mind the option. Can I upgrade to 4+ and then jailbreak? Some uses complained of sluggishness with the ios4. Please let me know, I'm sooo tired and am dying for a JB 3GS. Thanks all!

You can jailbreak at 3.1.3 with the phone itself at www.jailbreakme.com or get sn0wbreeze (windows) or pwnagetool (mac) and make a custom firmware for 4.3.2 to preserve the baseband and jailbreak

The sluggishness with the ios4 its on the 3G not the 3GS you will be fine on i0S 4.x.x

3gs is made to handle IOS 4.xx, so you need not worry about sluggishnes. If I were you I would go for 4.3.2 and you will love it.
If you don't want to preserve bb, then it is easy : Update itunes, restore to 4.3.2 and jailbreak it with Redsn0w RC14.

Good info everyone, thanks greatly!

I'm off to search again. I am interested in protecting my baseband(s) mainly for the sake for an optional carrier down the road or for future resale. However for my purposes I will be sticking with AT&T for mobile and Wi-Fi around the home.

I shall return
