There is an upside to being out of touch. Without texts, calls and regular requests to the 3G network for data, when the evening arrives I still have over 50% of the iPhone battery charge intact.
As to the plan to overcome the isolation, there wasn't one unless you count "trying to come to terms with it."
I didn't go to the pathetic Wifi area every night but I did check in sometimes. I also took advantage of any drives/walks that took me into a 3G area. But other than driving to try and find a poorly secured private Wifi network that I could access from the street or driving to a decent 3G signal there wasn't anything I could do, was there?
Coming to terms with my situation seemed to be the healthiest approach.
