I put a lot of thought into whether to leave the "Sent from my iPad" tag on my e-mails.
On one hand, I didn't feel the need to advertise my hardware. On the other, I thought it might excuse some of the inevitable ham-fisted typos I'd make with the onscreen keyboard.
I never considered there are people in the world who would pay for the privilege of having "Sent from my iPad" or "Sent from my iPhone" at the end of their messages.
According to the Financial Times, some Chinese consumers are paying around $1 per month to have the phrase "Sent from my iPhone" tagged onto their messages sent through the popular QQ instant messaging service.
The iPhone signature service requires that the consumers hand over their QQ usernames and passwords to merchants who then hack the accounts to add the iPhone tag.
The Financial Times quotes one merchant's ad as saying, "The iPhone is too expensive. If you don't want to spend that money, then fake it!"
