One of the major headaches facing all iPhone users is what to do should they lose their phone.
"I'm mortally terrified that I will lose my phone," said App World! editor, Mac Buck. "It's got my life on it."
This has led to the clinically identified condition, iPhone Checking, where the afflicted will either glance at their phone frequently, or at least pat the pocket in which their most treasured possession resides.
Help is at hand.
"I've just bought iStone," said Buck. "It's the most expensive applelet I've ever bought. But it does come with a free iPhone 3G."
The app, available from the iStore, links one iPhone with another, so that both are identical. Additionally, the screen of the iPhone uses the camera to identify what is on the other side of the phone, and renders this as a pattern on front screen. This makes the iPhone 3G virtually invisible when places against a wall, or on a gravel path, alternatively, several default stones are available, making the phone look like a pebble.
"What I've done," said Buck, "is to leave the iStone iPhone at home, hidden away in my garden, where I have it set to look like a stone. Now, if I lose my phone, I don't lose everything, because it's all on the iStone iPhone too. This is handy, as I use iHome to open my house, and I don't carry keys any more. They scratch the iPhone if they're in the same pocket, and I can't be having that."
Not everybody is impressed.
"I'm not impressed," said Ann Droyed. "The battery on an iPhone only lasts four hours. That's why iPhone owners always carry a charger with them. After that it will look like an iPhone 3G again. I bet nobody would steal it either. Who'd want one?"
