So I have a 3GS with the 3.0.1 redsnow JB... I want to go to 3.1... so i load pwnage tool in mac os, and it asks me to select my phone, so i select 3GS... it then says it doesn't find a ipsw to use. Do i use a 3.1 ipsw or what? Where's the place to get them? Dev team's site doesn't even reference where or link to them (odd).... Also, will i lose all the cydia apps i've installed or will those go over (ie winterboard, themes, sbsettings, etc?)? And will i have to reconfig email accounts, lose texts, etc?
