I got the iphone otb 1.1.2 and foolishly I upgraded to 1.1.3. I wasn't knowledgeable on the whole jailbreaking, hacking , unlocking the iphone situation.
so now i have some questions.
i recently have read that the 1.1.3 cant be jailbroken unless it has been unlocked/ or jailbroken on a previous firmware. and i cant downgrade to an earlier firmware.
why is this?
when will i be able to jailbreak this phone, if possible?
what should i do?

replies much appreciated
