a few simple things i couldnt figre out

1. Because i selected the second option when i connect the pc to the phone for faster file transfers, i couldnt get my phone to connect to activesync anymore. how do i set it up so i could connect it to activesync again?
2. simple and silly question. how do i set my mp3s as ringtone?
3. Is there a way or a program that could put all text message from the same person in one window with sent and receive messages? now im just viewing each receive message separately and not being away to look at wat i send out previously.
4. For the time on the today page. is it possible to change the 24Hour setting to 12Hour? Like it says 13:00 when its 1PM.

Thanks in advance guys.    

1. Start Button>Settings>Connections Tab>USB to PC icon

Place a check in the box "Ask about connection type when I connect"

2. What he said

3. In touchflo 3D, clicking on the message you are reading brings up the reply screen.  Above your text input box you should see all the previous messages between you and this contact.  Minimizing the keyboard will make it easier to read.

Thanks guys. Your helped have fixed all my 4 problems.

But heres two more.
5. When im in opera or viewing a picture, the wheel is supposed to help me zoom in or out rite? but its not doing that. it doesnt seem to work. I didnt even know its a wheel that turns.
6. When i put on a wall paper, it is only placed in the Today page. Is it possible it put it in every other pages? Or am i talking about a theme here? if so, know any good ones? =P
