From a previous post, I see that there is a store in London with cheap phones. I'll be in London, and could pick something up, but wasn't sure of the plans etc...or if the phone could be 'rented'. What is the best (cheapest) way to get a phone (once in London, or before)? I don't plan to use it a lot, other than to do a bit of planning when wifi isn't available (calling places or contacts....not web surfing). it would be used for 3 weeks
thanks!
