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 need advices or suggestions on what should I choose in terms of Audio playback technology on using my iPhone.

There is a lot of software to choose from but I want the best and want to know why it is the best because I heard some of them is not working perfectly.

Any suggestion would be very much appreciated.

I have created 9 custom ringtones  and I want to put them into my iPhone. But not all of them could be transferred. And even if I would choose 5 of it, only two or three are being synched into the phone. So what I did was search in the internet on what should I do with this. Luckily, I found a post on a Verizon Community forum which worked for me. So how did I do it? First, I unchecked the 'Sync Ringtones' icon and ran a sync. Then I checked it again and ran another sync, and it worked! All of my ringtones are now transferred into my phone, and I can also assign them to the people I used them with before.

I had the iPhone since the original 2G version with the black and silver cover. I upgraded it to iPhone G, then to iPhone 4. Now I have downloaded iOS 5 and I keep receiving an error stating that my message box is full.  I never had this problem before, nonetheless I listened and deleted some of my text messages from year 2008-2011. And then I leave my messages from the past few months. But then again I still got this message. I had my mailbox emptied and I am still receiving this message. Can someone please give me any suggestions on what should I do?

I want to know the battery life of iPhone 4. My iPhone’s battery seems to last a little longer. I have been using the internet for about 15 minutes now and at the same time I was sending text messages using Siri and have checked my Facebook page a couple of times using 3G and Wi-Fi. Please tell me about how long is the normal battery life of iPhone 4. Thank you.

I have a DJ app which I have been using in my iPhone and iPad for about 6 months now. I have saved a number of cue points, but when I updated my iOS 5 in my iPhone, it all got wiped out. Is it possible to update my iOS 5 without wiping all my saved cue points? Any advice will do. Thanks!

I want to synchronize my newly purchased iPhone with my MS Outlook 2007 contacts, calendars, and e-mail. I tried using the Google Calendar Sync, but it requires a Gmail account, and I don’t have one. Does anyone know how to do this?

I have an iPhone firmware of which I want to downgrade, before doing so I have to edit the list of IP addresses of which is stored in a file name “hosts”.

I can access the file but I can’t edit it. It displays an error message: “contact administrator” but I am responsible for administrative and backup operations.

Kindly help me where I go wrong?  

I am running Windows Vista on my computer. We used our own user accounts when accessing Windows. And no Administrator account is made. When I plugged in the iPhone 4G and tried to sync over WiFi, it was looking for iTunes at the administrator account though it isn't there. How can I access it on my own user account? Help please.

I am having a problem with Twitter application when opening in iOS 5: I can't find the news feed. I just got my new iPhone 4S then I backed up my old iPhone 4. Afterwards, I synched my iPhone 4s with my backed up files through iTunes. Then when I tried to open the Twitter app, it says 'Private account tap to retry.' I can see everyone whom I follow but I can't view the usual news feed. Can someone please help me figure this out?
