iPhones are convenient, sleek multitasking devices that allow users to talk on the phone, video chat, take photos, surf the Internet, watch movies, listen to music and more. All of these applications, however, reduce the capacity of iPhones. If you have a large music library or want more space than the 8GB iPhone 3GS, 16GB or 32GB iPhone 4 offer, there is a simple solution you can take to increase the capacity of your iPhone so that it can handle more of the files or applications you want to access.

  1. 1

    Purchase a wireless flash drive with a built-in media server. Look for one that supports standard SD/SDHC as well as micro SD/SDHC cards. Consider AirStash as one brand of such a device that is designed to work with an iPhone to expand its capacity.

  2. 2

    Use the AirStash to share your movies, music, photos and documents with any Wi-Fi-enabled device, such as your iPhone. Download photos directly from your camera to your iPhone by plugging your camera's SD card into your wireless flash drive and then upload them to your iPhone from the wireless flash drive.

  3. 3

    Load files onto the flash drive from your computer and then hold the drive within 160 feet of your iPhone along an unobstructed line of sight. Power the drive on by pressing and holding the power button until the green wireless icon appears and blinks three times.

  4. 4

    Open the Wi-Fi settings on your iPhone menu and look for the AirStash network (SSID). If using AirStash, open an Internet browser on your iPhone and type "" into the search field. Hit the "+" button at the bottom of the iPhone page and choose "add to home screen." This will add the wireless device to the home screen of your iPhone making files on the wireless drive easy to access.

Tips and warnings

  • The flash drive includes a lithium ion battery but can also be charged using the USB port on your computer.
