Changing one's clothes during I'tikaaf

Q: I understand that one is allowed to change his clothes during Itikaf. In the Haram Shareef at Makkah and Madinah since there is no privacy, is it ok if one changes his clothes in the toilet when one goes to attend nature's call? Of course care is taken that one does not leave the Haram only for changing the clothes but does it when it is unavoidable to leave to fulfil the need to go to the toilet to relieve oneself.

Divorce via email

Q: My son and his wife lived together abroad. She got a baby but unfortunately died before birth. On the advice of a doctor, she came back to Pakistan for her treatment. After sometime, my son sent an email through his computer, and wrote the divorce to his wife's email address. Divorce without any witnesses and signature. Both would like to reconcile and patch up now. I would like to know according to Islamic Shari'ah that has talaq has taken place through email or not?
