when i try to open camera app or safari, iPhones blacks out, unlock screen appears. I slide to unlock and find myself again on camera or safari, the process repeats until i reset.

Ive restore but, itunes show 250mb in the OTHER category, so i still have all my old apps.
the problem started when i tried to install the xsl, doc, jpg, pdf viewer( the ones that let safari read local files ) , it need jiggy runtime, and some other stuff, also , camera pro was installed.

how can i full restore the iphone, so wathever file its f*ed up. Restore function in itunes dont sove it.


tx in advance
