I'd like to get the 3.5 kernel in 12.04.1 but don't want to add any sources to my repositories that won't be supported until 2017. 3.5 hasn't automatically showed up as an update since the release of 12.04.2 - still stuck on Adding the "upubuntu-com" source would probably do it, but isn't that going to break at some point before 2017? I just want the officially supported, stable 3.5 kernel for 12.04.2.
