Hi. I've just jailbroken my ipod touch from 1.5 to 2.1firmware. Also with cydia&installer already. But I am so confused about these tools. I downloaded some cracked games in ipa and pxl forms, but I could not install by itunes8 or ibrickr or ibus. Someone says that the 2.1 firmware not allows ibrickr and ibus. Then what shall I do? Does anybody know how to install this kind of files? Pls advise. Thank you.
