I noticed something similar, but note OFCOM is allowing operators to use any part of their allocations for 4G services. I'm wondering if they're reusing some o

  The standard PR seems to be that network operators claim they aren't doing this and continue to develop their 2G and 3G capacity in parallel, with any degradations in performance being due to supporting increased loads and therefore contention on those 2G and 3G networks. Meanwhile, just about everybody who actually uses mobile networks seems to tell roughly the same story that I did before, and there seem to have been occasional more rigorous/scientific surveys that showed a definite, measurable drop in service quality on 2G and 3G over the relevant time period.
