I have iOS5.  I want to stream selected photos on my iPad but it’s not working.  What’s wrong?  I also want to share documents between my iMac and iPad.  How do I do this?

When I open iCloud, default applications like Address Book, Mail, Calendar and iWork appear.  I believe they are synchronized but I don’t know how to access my documents from Open Office.  I tried dragging and dropping a file into iCloud but I still can’t see nor access it.  How do I do it?

I tried to sync my iPhone 3 with my new computer.  During the process, I lost my contacts, pictures and music.  Luckily I have them on my iPad.  How do I copy them to my phone?

I am running Windows 7 Ultimate (32-bit) on my laptop and I can’t install iTunes.  The error says that the program is an invalid Windows 32-bit application.  Is there a particular version of iTunes compatible with my OS?

How do you delete ringtones that you added with Ringtone Maker from iTunes?

I seem to have problems with the battery of my iPhone (version 4.2.6 and my modem firmware is 1.0.05).  When I went to work I had 98% battery.  I had no service and I am on EDGE network.  After 6.5 hours of moderate usage, my battery went down to only 9%.  I have an officemate with the same phone and network and almost the same settings, but hers went from 79% to 66% only.  My Wi-Fi is off, all apps are exited, and my screen is on auto-brightness.  My weather updates every two hours.  How come my battery drained so much so quickly?

I was communicating with my dad via iMessage, but later on it seems that some were being sent as text messages.  Can I force iMessage exclusively for him?

Everytime I turn on my iPhone 4S, it always prompts for my password in iMessage.  Is that normal? 

How do I configure the settings so that it will stop asking for my password?

I have downloaded some apps for my iPod, but when I open them, nothing happens and it just goes back to the home screen. Is there some bug in the iPod or is it with the download?

Which Bluetooth headsets work with iPod Touch (4th generation)?  I want to use it for U streaming and I would like to use the mic from the headset.  The forums I have read are about older generations.
