Despite just being around 15 month since its release the htc one s will not receive any further software updates! I thought there was plans to release sense 5 on the device but it looks like this won't happen 
Having said that my phone is still on android ICS 4.0.4 and haven't bothered updating to jellybean 4.1.1
