iTunes 9.0.2 removing iPhone firmware
Very interesting, iTunes 9.0.2 removed both iPhone firmwares (including a custom made one) from my "iPhone Software Updates" folder. As always, right after updating a few iPhone apps through iTunes (version 9.0.2), I checked the Trash to review the removed apps by iTunes. However, the surprising fact is that both ipsw files were removed, and placed in the Trash folder.
Either it's a bug, or Apple somehow decided to secretly get rid of "iPhone1,1_3.1.2_7D11" file. My temporary solution from now on will be a backup from any ipsw software firmware, anywhere out of the iTunes controlled additional folders.
