It's great that your Dad has gained weight - it will certainly be a plus should the Rad Tx effects start to really make things difficult. The worst time for my son was right at the end of Tx and a couple of weeks afterwards. So if your Dad can be prepared for this eventuality, it will be a little easier to get through it. You and he have had such good news so far with his health and how he is handling everything. Plus - his new iPhone! Yay! (I just got an Apple wireless keyboard to go with mine and loving it!) Keep up with the great updates!
