How to share files through iPhone's WiFi?

I have an iPhone 4S and i like to share some files on my phone with others. As long as Apple has not enabled Bluetooth, i would like to use wifi. You see, where there already is a wireless network to connect to, it is a piece of cake to share any files on iPhone hats off to ifile, but where there is not such a network, how can I create one with my phone? I have tried mywi but it does not enable ifile's wireless file sharing and I prefer not to use airblue sharing.So, any suggestions?

You can't iPhone suck with Samsung galaxy s3 you can't tap phones together to share files
