I have a 1.1.2 OTB iphone fully unlocked and functional except for SMS and keypad in phonefunction crashing to springboard.
Heard that this can be solved with selecting my country (Australia) in iWorld.
The problem is that iWorld doesn't show up in installer. Is it

A. removed from installer
B. something wrong with my iphone?

(i have had iworld installed previously but uninstalled it again)

Whatever the reason is, how can i solve this?
