I have a bricked iphone 4. It is jail broken and when I did the erase all settings and content it now freezes at the apple logo. I did the little hold this and that to get itunes to recognize it but itunes wants to restore it and update to the newest firmware. It starts a download for 4.3.3 which is 666mb. I can't download a file that big on this wifi network I use...don't ask. Anyways when I got my phone new it was in recovery mode and somewhere down the line I know I have downloaded a firmware file through itunes to update, but when I find the itunes firmware folder on my PC it is empty. Any suggestions? Thank you.
