On a separate note my phone came with 4.1 when I got and JB it was a breeze, but I had issues with full 15gig storage space being used up even though I only had 55 apps installed, so I done a restore with itunes without knowing the implications of the firmware being upgraded. But what it is I read somewhere that if your using firmware 4.1 and you use cydia, if you 'click make my life easier' in cydia it would save your firmware somewhere should you need to downgrade at a later date. Now I'm 99.9% sure I done this but I have no idea what I need to do to try and downgrade back to 4.1, I tried using Umbrella as some suggested but nothing, and ideas?
Thanks
