I find Dropbox on the phone really useful. I find it handy to save PDF confirmations of hotel bookings, flight reservations, eTickets, etc so I can easily access them when I travel (just "favourite" the document on your phone while connected to WiFi or in an area with reception and you can have offline access too). Sometimes when I know I need to go somewhere and wait (e.g. the DMV) and I want to just read a PDF related to coursework or research, I can quickly move the file to my Dropbox on my computer and then it's also on my phone. As I wrote somewhere else, I find it tough to regularly read academic PDFs on a small screen (two columns, figures etc are tough), it's pretty handy for once in a while.
 
I use Google Calendar as my main organizer and basically everything is sync'ed up with my laptop through Google Apps (documents, email, calendar etc.)
 
Not directly related to school, but apps for getting coupons for the grocery store etc. can save you some money on a grad student budget too. And PayPal is a handy one to pay your friends back when you all chip in for pizza or drinks or whatever. 
 
My campus is really well mapped on Google Maps, so I find that really handy when I need to go to a new building (grad students don't get around campus much!). 
 
Finally, ConnectBot is a really handy app that lets me use ssh to log into my work computer. I can then check that status of any programs I'm writing etc. In theory, you can use it to work on your computer as if you had a full keyboard but it's not very easy to write code on a phone! I use it when I need to check the status of my code while I'm away from a computer. Although I've really only done this a handful of times--it's rare that I need to know the status of something so urgently that it cannot wait until I get back to my desk.
 
That's all I can think of on my phone for now!

I am in no way justifying the unprofessional behavior of your cohort but part of growing up is learning how to deal with people you don't like. You probably won't want to be friends with with most of the people you encounter in your career. That's okay. You're there to do good research, learn as much as you can from your mentor, and be polite to those around you. It's a shame your peers are less ambitious and not the type to encourage you to do you best. Let their comments bounce off of you. Keep working hard and getting funding awards. It's better not to disclose funding to peers, anyway because it breeds jealousy and greed. My boss recently obtained a $12M grant and professors are coming out of the woodwork, giving me their sob stories as if I can somehow relay that to my boss and get them a sympathy grant. The real world doesn't work that way. The best way to handle your cohort is professionally. Kill em with kindness. You'll probably be their boss someday.

First good stats one of the year coming from a Harvard PhD rejection:  "As a patriots fan, New England really hasn't come through for me this past week."
 

FTW!!!
 

I wanted to post the following to the results page but discovered that lengthy notes are moderated. Nuts!
 
Highest weighted and unweighted GPA in the history of mankind. Perfect GRE scores, including for subject GREs both inside and outside of my field (just for fun). Exceptional LORs from the most acclaimed professors in the entire universe (3 from Earth and 1 not of this planet). A bajillion published first-author papers, short stories, full-length novels, and a zillion forthcoming. Volunteer experience out the wazoo. Hardly surprised. I knew 100% I wasn’t going to be accepted but applied anyway just to have options. Had I been accepted, I wouldn’t have chosen to go here fo’ sho’ as it would have been a TERRIBLE fit. In any case, I got way better offers (six-figure guaranteed scholarships + health insurance + deluxe flex meal plan + reserved parking spot) from every top-ranked school in the galaxy, including ones I didn’t even apply to, along with very personalized congratulatory hand-written letters from all the faculty and their immediate and extended family members, plus gold-leaf-framed oil paintings of their pets to boot.

I will be attending the University of Miami for Clinical Psych.

NOT a funny rejection, but one that is absolutely heartbreaking.  This is a student with excellent GRE scores and a killer GPA who wrote:
 
 
Whoever you are, just know that I wanted to reach through my screen and give you the biggest hug ever.  This process is a killer, but please remember that this school's rejection does not determine your worth!  
 
That statement may have sounded cliche or cheesy to the point where it needed nachos to go with it, but EVERYONE should remember it!  Just because you didn't fit a program's standards does not mean you're worthless.
 
Now, this person's statement could have been completely sarcastic.  If so, then I'm sorry for getting all sappy!

You know,maybe some are really actually over qualified. Schools accept people who have some learning to do. If you're already so successful and good at what you do, maybe you don't actually need school as much as the next guy!
