4G should be used exclusively for LTE, which is the new standard and provides increased speeds over 3G. You can get speeds in excess of 100Mb/s on LTE, again, theoretically.

Neither HSDPA+ nor LTE would have qualified as 4G under the original definition, which required 100 mb/s while moving, and 1gb/s while stationary.
The 4G definition was redefined in 2010 to include both HSDPA+ and LTE (even though LTE is much faster). I don't think it makes much sense to include them both in the definition, but they both meet it.
In the real world, good HSDPA+ speeds are around 10 mb/s and good LTE speeds are around 40 mb/s.
