I've sampled the WiFi on Virgin and East Coast in the past. Every time it's been comprehensively unusable; either it remains loading indefinitely, or it spits out an error page.
3G coverage isn't continuous but when I tether my phone, it either works, or it tells me the connection is down.
From memory, we had a similar experience with Grand Central (KGX to HPL and return) when we visited the UK in July 2011, and ended up using 3's coverage (where available) instead.
We'll be back over there in a couple of months, so I'll see if it's any better this time.
