Sometimes, the local storage on your iOS based device is pretty close to full. Of course you will need an additional storage for your iPhone, iPad, or iPod Touch. It is even better if the external memory can be easily access on your computer. It means that you have to try the PhotoFast i-FlashDrive. It is an accessory that will be launched soon, which has a USB plug at one end and 30-pin dock connector on the other side.
See the picture for a better imagination. With this method, it is easier to access your file from your iPhone and computer. This accessory is available from 4 to 32 GB, coming along with an iOS app which can be used for file management, MP3 playback, and backing up your contact. The 32GB model will cost $180, but I don’t think it will be a problem as an iPhone users are always willing to spend more for accessories.
Actually, you might think that having another accessory for your device is complicated. Especially if it is only for file transfer, when uploading it to the cloud service is much easier. But if you want to have your iDevice to work as a flash drive (we are talking about i-FlashDrive here), it is your decision.
