  1. I have a week 41 3GS, I’ve read that if I try to downgrade my 6.15.00 bb, my phone will be bricked. Is this true?. I have signal and GPS, but the problem is that Im stuck on version 4.1. So I can’t use facebook, whatsapp, etc. What could I do?

    1. Sick of the spam comments ?, when i needed to get my phone unlocked i went to iphonegeeks(.us). Check thsi site out for sure

  2. Please reboot the device into normal opration mode, then perform e clean “slide to power off”, then try again. I got this error while downgrading can you help me
