Okay so I want the 4.1 speed.
I have an iPhone 3G on 4.0 and i ONLY have a t-mobile sim card.
If i could borrow a friend's att sim card, could i do this?
1) Use TinyUmbrella to upgrade to 4.1 ( Not upgrading baseband)
2) Use att sim card to activate and then use jailbreakme.com on 4.1 ( Not sure if it works on 4.1)
3) Download ultrasn0w ( since i have 5.13.04 on 4.0, if i upgrade w/o updating baseband)
Would this all work?

jailbreakme.com doesn't work on 4.1; that loophole was closed with 4.0.2. The newest redsnow *kinda* works with 4.1, but there are problems being reported (cydia not working, phone.app missing, etc.)
As of now, there is not a good jailbreak for 4.1 on the 3g.

You're stuck until an official jailbreak for 4.1 is released.

You should not restore to 4.1, no jailbreak. If you want speed, downgrade to 3.1.3 again.
