… And I’m not sure if it counts as a GQ so I put it here. My phone, Sony Ericsson P910i, has infra-red capability… So in theory it should be able to change channels on TVs. My old PDA with infra red could do it. Why has no bright-spark made some software for my phone to do it??? ---

perhaps your phone’s infrared transmits within a different frequency band than does your TV? Just guessing. ---

By way of bumping this thread… If I remember rightly my PDA (and other such devices with this capability) could be adjusted to control any and all popular TVs, meaning they probably could adjust their frequency accordingly.
