I bought an iPhone two months ago. The promoters in the shop give me a few instructions, but no more warn on particular service provider, like AT&T. After the purchase, it took me just several hours to jailbreak it, just using a tiny application downloaded from the web. Then I can use almost all its functions, such as phone, iPod, and internet. It’s really an amazing creation, which many powerful applications can run smoothly on.
But there was still something made me uncomfortable, that is, the developers of the Apple designed iPhone in such a way that, without using iTunes, I couldn’t transfer any music or movie into it. Using iTunes, even if I synced music and movie into iPhone, I just can’t sync them out. And all media files will be cleaned up the next time I sync other files in. Furthermore, besides media files, I even want to copy files of other format into it, and utilize it as a portable HDD. The capacity of my iPhone is 4GB, much larger than normal cell phones, even with a TransFlash disk, and larger than the common USB flash disk.
By the way, the weight of iPhone is 120g. Most of it must be the metal shell. It’s much heavier than my former Nokia. Taking the iPhone, it’s just inconvenient to take another portable HDD.
There is still no effective way to jailbreak iPhone, in order to import or export files directly. So, it’s necessary to install some software in the computer as an accessory.
When searching on the web, I found many applications to rip music into iPhone, but few to copy other files between iPhone and computer. And almost all for copying common files is just free for trial.
