Uhm... don't mean to be a naysayer... but there's so many things wrong with this thread, I don't even wanna get started.

Still, my best bet is: 1.1.1 firmware = you're temporarily dead (until developing folks come up with a solution).

well.. if you insist to using your phone using firmware 1.1.1 then i'm afraid you have to wait until the dev team have cracked it up. so until that moment comes you can't use it as phone.

in other way of solution you can downgrade it using the method in this link
