Can someone from Vodafone please let me know if the the 4G rollout has been completed, or is it still underway>? Reason I ask is I get perfect 3G signal at my place but 4G is patchy, which leads me to believe the cellsite I'm getting my signal from hasn't been upgraded...and no, this isn't my phone as another phone in the house has the same weak signal (even going outside doesn't make any difference).
