i just need a steer in the right direction and am not sure where to look first. i havent been on this site since i had a psp all those years ago ( nice new layout) anyway i just bought an 8 gig 2g iphone ( 40 bucks on craigslist **** YES ) and it is already jailbroken and unlocked. its on 3.1.2 but i was wondering if i couls use the 4.0 os on it ( i want to get the ibooks app and i like the feature that lets you set your own backround picture/ put apps in a folder)
but what i want to know is,
can the 4.0 os be jailbroken AND unlocked ( i use t mobile) for a 2g iphone and will the cool features i mentioned work?
is there a guide that will show me how without bricking my iphone?
can an iphone even be bricked?
last but not least, is there a way to actually remove ( not hide) some of the apps the device comes with? (weather stocks voice memos and calculator)
thanks you guys in advance.
