Hi, i've just bought new, but second hand Kindle Keyboard. Unfortunately it's the version with special offers (that guy didn't tell me that > he will burn in hell). I don't register it yet and the Kindle don't show any offers, even screensavers are normal as on K's without offers. My question is, have somebody experience with these offers ? I read, that offers will show after registering. What about de-registering, will offers go away ? Or, if I ever register it, they will appear for ever ?
