question about 3gs upgrading from 3.1.2 to 4.1 - GSM-Forum

shadowz01 · 10-20-2010, 10:39

Hi to everyone~ i'm new here

I have an unlocked 3gs with
version: 3.1.2 (7D11)
modem firmware: 05.11.07

I'm just wondering is 3gs unlockable after upgrading to 4.1? and what should I use to JB + unlock my phone ?

thanks~

after upgrading you may face NO Service ........due to baseband version
