Moving to Bhutan

Hello.

I am moving to Kanglung Bhutan to work at Sherubtse College in October. I would like some information on Bhutan before I arrive and hope you all will be kind enough to assist me. Upon arrival, I will need telephone and Internet service for my iPhone. Is there service available for smartphones and how might I get service quickly? Can I contact a company now from here in Thailand (I currently live in Thailand)? I also have a Mac computer - are there support shops that work with/sell Apple products? What is the weather like and what type of clothing should I bring? How is the food? I am mostly vegetarian - is vegetarian food available? As an ex-patriot, will I feel a part of Bhutan society or will I be reminded that I am only a visitor and not to be part of Bhutanese society? What are some things I will like about Bhutan? I hope I have not overwhelmed you with my questions and that I hear from you soon. Thank you.
