I just changed my user name to my e-mail address on my iMac. It works fine there but when I try to use my iPhone it still shows my old user name and will not let me enter??

There is no user name needed to "enter" or use iPhones...
Assuming you mean your iTunes Store account ID:
Settings > Store > tap ID > sign out > sign in with new ID

Hello Tholc
The reason for that is the screen motion that is enabled. With certain photos and how they were taken, they will be zoomed in so that there is no black space on the photo.

HT5622 I have changed my Apple ID, but when I try to login to iTunes it still shows my old Apple ID thus not allowing me to log in. How do I change this in the system?

How do I change my Apple ID when I go into iTunes. It seems when I log into apple web site it recognizes my new Apple ID, but iTunes does not. How do I change my iTunes Apple ID?

Have you change your apple id on your iphone?
settings - store - apple id - sign out - then log back in with desired id.

HT1212 my iphone is frozen on the lock screen and will not let me enter my passcode, I have held the home button and power button for up to 1 minute and plugged it up to itunes because its locked it wont work? i need help

i have connected it to itunes like i was told to do and it wont do anything because its locked with a passcode and its frozen on the lock screen and will not let me enter myt passcode and after a while it just shuts off, it has been doing this for almost 48 hours. I was told to hold the home button and power button to shut it down and that I could then restart it and it would work... Nothing has helped, What can I try???

Reset the device by pressing and holding the home and power buttons for 15-20 seconds until the white Apple logo appears.
If that does not resolve, restore the device via iTunes on the computer.
If all else fails, take the device to Apple (or whomever provides support in your country) for evaluation and possible replacement.

When I bought my iPhone 4s, a friend activated it for me using his email. Later I changed it to my own email on iPhone website (iCloud A/C). But when I try to update, I found it still shown my friend's email and I don't have his password. What can I do?

In addition to what FelipeV is telling you, I advise you to contact your friend and have him remove the iPhone from his apple id through icloud.com. Otherwise, if in the future you want to update the iOS or restore the iPhone for troubleshooting a problem, you may find that you cannot activate it again due to the feature Activiation Lock in iOS 7.
Once your friend has done this, you should deactivate Find my iPhone on your iPhone iCloud settings and then activate it back with your own Apple ID.

HT1911 How do I get my Ipod touch 4th generation to change my email address? I have updated my account on Itunes, but when I go to purchase or update it still shows my old email address.

I recently chenged my email address on Itunes. When I plugged in my Ipod 4th generation Itouch, it still shows my old email address.
It syncs everytime, but the old email address is keeping me from making other purchases. How do I fix this?

In order to change your Apple ID or password for your iTunes account on your iOS device, you need to sign out from your iOS device first, then sign back in using your updated details. (Settings > store, scroll down and tap your ID)

My iCloud account is giving my old email address by default and will not let me enter a new one.

help! my icloud account is automatically prompting me to enter the password for my old email address that I never even used with icloud. I no longer have access to this email account. Also, it does not let me edit or change my email address. help please!

Go to https//appleid.apple.com, click Manage my Apple ID and sign in with your current iCloud ID. Tap edit next to the primary email account, tap Edit, change it back to your old email address and save the change. Then edit the name of the account to change it back to your old email address. You can now use your current password to turn off Find My iPhone on your device, even though it prompts you for the password for your old account ID. Then go to Settings>iCloud, tap Delete Account and choose Delete from My iDevice when prompted (your iCloud data will still be in iCloud). Next, go back to https//appleid.apple.com and change your primary email address and iCloud ID name back to the way it was. Now you can go to Settings>iCloud and sign in with your current iCloud ID and password.

When i try to connect my iPhone 4S into iTunes through wifi or USB it will not connect the other thing is when i hook up my iPad into iTunes it will connect through wifi but not USB? Now is this a issue with my iPad and iPhone or is this iTunes?

When i bought my iPhone and my iPad they both were on iOS 7.0.2 i updated them shortly after thinking the new iOS 7.0.4 was better. i see its not but they both worked great with iTunes before and after the update. My question is why is my iPhone not connecting to iTunes? it will not connect through USB or wifi and i know that the setting to do that is turned on. my iPad connects through iTunes through wifi but not USB. This isnt making any sense but i wanna know is this a iTunes issue? or is it my phone and iPad??

This can sometimes be the result of a faulty/damaaged USB sync cable. Do you have another cable you could test it out with?

I cannot print from firefox. I can print from open office. It seems to have something to do with when frames open because in IE, I can print a whole page, but when I try to use a print button embeded in a page or frame it does not work.

Cannot print from firefox at all.
In Internet Explorer, I was able to print by pushing the print button, but when opening a frame, like in mapquest, the embedded print button brings up an options window that has print frames options in it, but when hit OK in this box, a second error box comes up with a yellow exclamation point and nothing prints. I have a feeling that it is the same problem with both browsers, but would prefer using firefox. Can you help with this?

Yes, I tried that.   The files were ordered by their original numbers as imported from the camera, but I batched them through Phocoshop to downsize all of them into a more manageable file size.   I opened that destination folder from quick time from where it said select image sequence.   I clicked on the first one and opened it.   The result was a large image with an arrow indicating a movie was ready to go.   When I pressed the arrow, though, I realized it had only imported that one frame so there was no movie.   The files are Jpgs and are about 450 KB each.
    To your knowledge are there any links to iMovie tutorials or quick time tutorials that may address this situation? Maybe there will be one I haven't looked at yet.
    Thanks

It gives me the following message and will not let me enter admin to delete it.

Running windows XP, encountered a problem updating iTunes. Now cannot re-install it. when i try to re-install, the website acts as if nothing is wrong and will not reinstall. How do I re-install iTunes, when the website detects that it is installed?

I am running windows xp and tried to download the latest version of iTunes 11.1.4 for windows xp. Unfortunately it did not install correctly. There was a error message: Microsoft Visual C++ Runtime Library, Runtime Error!, Program:C\Program Files\iTunes\iTunes.exe, R6034, An application has made an attempt to load the C runtime library incorrectly. Please contact the application's support team for more information. Then,when I close that box, another box appears that states: iTunes was not installed correctly. Please reinstall iTunes. Error 7 (windows error 1114). When I attempt to reinstall iTunes though the Apple iTunes website, nothing happens ( no reinstall) presumably because it detects that it is already installed. How do I work around this problem to reinstall iTunes?

When I try to use TD Webbroker to open my Tax Documents in eServices they will not open and it hangs up my Firefox. I am using windows 7 and if I try the same procedure with Internet Explorer it will work. Any ideas?

I am using Windows 7 and AVG

But I can't... find... it... It's not there.
Unless you're talking about the entire Mozilla Firefox folder (which isn't what the thing you copied says,) there is no installation folder.
