my iphone keeps freezing on the slide 2 unlock part. I unlocked using independence or w/e and Downgraded to 3.9fb. What is wrong? I tried restoring, DFU, and reunlocking... Nothing works.. i drained the battery and turned it on again. Worked for one night but froze up again. Is the problem with the baseband or bootloader? By the way its FW version is 1.1.4 right now. Need major help.
