I actually just got back from spending a month in the UK, so I can tell you that you should put it in flight mode, and keep your wifi radio on. The drain of just the wifi radio and nothing else isn't too bad. In London, there were so many open hotspots it was almost like I had cell coverage. Also I would recommend downloading skype (the skype 3.0 beta if you plan on texting) and buying some skype minutes if you haven't already done so. Another bit of a warning, when I was over there I was able to call American numbers just fine, but when it came to dialing UK numbers it was giving me a hard time. Not sure if that was my noobness showing or if the WM version doesn't have that capability, Not sure where you're going so I don't know how much that helps but nonetheless have great trip!
