i have a 2006 mustang it has the factory radio in it and a AUX button but no AUX input. so my question is what kind of cable do i need to play my phone music threw my radio? is it even possible? or do i just need a new radio.

I reinstalled my operating system and need to download the software that backs up my iphone. I tried plugging the iphone into the computer and it asked if I wanted to backup my pictures, but it did not open the iphone program. (Is it iTunes?) Anyway, I googled it, but all I saw was an update for the phone itself.

Where can I download the backup software?

I really hate the music iphone comes with and you cant use your ipod music as your ring tone so i was wondering if there is a way i can do this.

Also is there like different themes you can put on your iphone?

Thankyou : )

I just sold my iPhone and are planning to get another one. I bought all the music that I have on my current iPhone from iTunes. My iPhone is currently synced with my laptop and so is the music. How will I transfer the music onto my new iPhone? Or how will I gain access to my music once I got my new iPhone?
Im getting a new iPhone, not a new computer

Accidently deleted a video on my 3gs iphone after taking it.
Is there a Completely FREE program that is virus free that will recover the video?

I am currently looking for a website which hosts unlimited number of videos for free and also supported for iPhone video streaming.
Thanks for any BEST answers.
