OT: Sprint Network Near Eastgate in England

From: William Wade 
------------------------------------------------------
So I and my wife have different phones. By different proxies, we are on the
Sprint/3G network. Only near our house, i.e. our local tower, we often have
our phone flip to +5 hours and a while later flip . It has gone on for a
while. I even force updated the timezone info on my wife's phone where I
have root.

Anyone else have a problem like this? Know what is going on? Who would I
call to report it and actually have something happen?
