[ccxr]

Hello everyone im new here and i like forum a lot.
So i have few questions:
1. Im on 4.2.1 (3GS 32GB) it's tethered jailbreak!
2.Phone is not SIMFREE (unlocked with ultrasn0w BB 06.15.00)
How is the best way to get untethered?
Apps,Photos,Songs and other all backed up
Thanks in advance!

You should not be tethered at 4.21 at all redsnow or snowbreeze for 4.21 will do the trick but you'll need to restore with a custom pkg first since its very dangerous to jailbreak on top of another.

You'll never be able to fix your baseband problem though to go back to stock firmware so you're likely stuck at 6.15 forever

You also might have to use tiny umbrella since apple stopped signing 4.2.1

Grab snowbreeze for 4.21 download 4.21 firmware, patch it with snowbreeze and restore in pwned dfu mode (snowbreeze will walk you thru process)

So basically i dl snowbreeze and also i have 4.2.1 because i must "Boot tethered now" and just patch it and restore in pwnd dfu?

Personally I would use sn0w to make a custom 4.3.3 Ipsw and then use that on iTunes

If your new to jailbreak, go on YouTube and look at dinozambas2, he is amazing and I learned everything from him
