I found a way to store any files in my iphone (and easily use them in any windows pc). I always wanted an easy way to store files in my iphone but I didn't want to void my warranty by jailbreaking it. About a week ago as I was browsing the net I found this page (iattachfilez.atwebpages.com). At first I laughed that someone made something so stupid... but then an idea came in my mind... could this fool my iphone? So I downloaded it and "disguised" a zip file containing everything I need to carry with me. I then sended it via e-mail to my iphone. It was recognized as a photo and it allowed me to store it in the photos. Then I went into another pc (without iTunes) and plugged my iphone. The pc recognized my iphone as a flash drive (as it always does to get my photos) contained the "disguised" file. I then copied it in the local drive, decoded it through the utility and IT WORKED LIKE A CHARM.
