Yes mate...connect to iTunes...Back Up iPhones....Update iPhone to 5.1.1 with iTunes....then Jailbreak with Absinthe 2.0.4.....Also make sure you have the latest iTunes installed on your computer...

[billy2]

THankd m8 i have all my shsh blobs saved in cydia will i need to save them to my pc ??? if so would you know how this is done

cheers

[fijiman]

SHSH not needed for what your doing....

Make sure your on the LATEST version of iTunes.....
All you will be doing is a standard firmware update....
Make sure you Restore 3GSto 5.1.1 as a "New Device" with iTunes...
Jailbreak 3GS as soon as your on 5.1.1 then think about restoring from backup on iTunes if you want...

4 jb with absinthe-win-2.0.4 ( will i lose my shsh blobs in cydia if i JB again ???)

If you need to unlock you will have to make sure you preserve your baseband (05.13.04)...

Otherwise it will be updated to a version you cannot Unlock....

[billy2]

thanks m8 would this be a good guide to follow ???

Yes a good guide....as long as you can follow/understand all the steps....

[billy2]

once again thanks for your time fijiman


ok guys is this right

1 preserve your baseband (05.13.04) with redsNow

2 update iphone ISO in itunes then (put phone in DFU mode)

3 reinstall preserved baseband made with redsNow in itunes

4 jailbreak again with redsNow OR absinthe-win-2.0.4

cheers

[fijiman]

No mate...
1-Download 5.1.1 firmware to computer
2-Use redsn0w to build a custom firmware(this will preserve your baseband)
3-Then use iTunes to install the custom firmware onto your 3GS....

Good luck

Ok your using sn0wbreeze now....the steps you listed are correct...don't forget to BACKUP with iTunes....
