I am probably another in the minority, but I agree with Israfil, even if an iPhone is super cool, all the iPhones in the world don't explain parent abandonment. A kid is not a reason to Stay married, but even with divorce and moving to another state, there is phone calls, holiday trips, and visitsto stay connected with your kid if you are interested in. So Chandler might have a crappy life and Helen might be a Saint to him, but that doesn't clear how terrible mother she is to Landon and the emotional scars She left on him. So in his position, not calling her mother is the least I would do, probably calling her less pleasant stuff or not talking to her at all would be more likely...
