I am trying the trial edition before I purchase the one-year subscription, and I have noticed a few annoying things. The first one being dates. Whenever I add a birthdate or anniversary to my iPhone, it syncs to my Mobileme account, but the actual date is sometimes a day ahead of the day in my phone. The day does not change on the phone and I have to manually change it online. The other problem for me is the contact groups. I added a few and places some names in there, but sometimes some names would disappear from the group online. When I look at my iPhone, I see the group titles, but when I go into the group, there are no names in them. (But there are names in the groups online.) I can add a name, but it only brings me to add a new contact and not add contacts from already entered. After a while, I got mad and just deleted the groups from online. I look at my iPhone, and the groups are all still there (well except for one group that did not sync in the first place). My MacBook does not let me access the option to sync and there are no birthdays on my calendar online. I called Apple and they had me talk with a Mobileme specialist and he put in some kind of form stating what bugs are on it.
