Update
Ok all...I have reorganized my apps back to the order they were and here are the results of opening everything on page 1.
1) Settings: Everything under settings looks and remains the same...so far. Have not dug into anything but first selection. All looks and runs the same.
2) Calendar: Still syncs with my Outlook 2003. No data, appointments or changes noted. Unable to lock onto my Google Calender as it does not seem that the CalDAV option is activated yet. If I were to guess, it should work the same as contacts and allow me to select google under the Info tab when plugged in. This is not showing...yet.
3) Contacts are the same as the old version except one addition is now showing under groups. Any Exchange accounts you have built in now show a Global Address book for that exchange. Example: I am a college student and it is set up under an exchange account...it now offers me the ability to look up the Global address book and see all address's and use them to send/call/etc.
4) Emergency data is all still there the way I built it and the App works fine. I am a heart patient so this is improtant.
5) Calculator still looks and works the same
6) Maps...I will post more about later but at least what you are use to is still there.
7) Photos...Same as number 6, Do not see anything different yet.
8) Camera...BUG...the icon is missing for camera roll and is a hollow square but camera still seems the same...will test and report if different.
9) Weather Channel App still works and behaves as it did before but with its most recent update.
10) Google App...Still works but seems to be a little less accurate. Does not recognize clearly spoken words as accurately as it did before during the verbal search. May need calibration.
11) Evernote...Works fine and maintained all of my offline favorites, folders and still works as it did before.
12) Listomni...Works as it did before...Kept all of my To Do's without change or loss of schedule. Kept all lists and folders.
13) BillMinder...Maintained all of my Bills/Accounts/Due Dates and badges for upcoming payments. No change to functionality.
Still have 7 more to go through on Page 1 but everything works as it did before except for the changes already noted.
I have not had any crashes, slow downs or problems with the 3.0 install. iPhone still runs as well as it did before...and NO it is not QUICKER

!!!
Will post again after more testing, stay tuned...
