Invalid checksum for iTunes? ... can't download large apps?

I've noticed two things.
First, I've tried to download iTunes 11 from both the app store and a straight download, and, both ways (and every time -- 7 tries now), I get an invalid checksum. I've downloaded from Chrome; I've downloaded from Safari. I can't imagine the source is the problem, so what's happening there? My network connection seem otherwise solid, based on my ping rate to California, and standard web use.
Secondly, iTunes 10 won't download large apps. Neither the 'Magic the Gathering' update or the 'Grand Theft Auto: Vice City' app will download. (Both of those weigh in at over a gig.) At some point during the download, I get the warning, "An unknown error occurred (-50)." Smaller apps seem fine.
This is with a late 2008 13-inch Macbook Pro running 10.8.2.
Help? ... and thank you!

Just need to find a way to get a hold of someone who can fix this.

Itunes will not download large apps to my iPhone......HELP

I have downloaded 4 apps on my iPhone that are over 20MB and it says to connect via wi-fi or to itunes to download them, but everytime I do, they won't complete and download.....any ideas anyone?????

Anyone?
Apple won't help me unless I pay them first

I do not have access to wifi - I use cellular data only to access the Internet. How can I download large apps without jail breaking or wifi? Frustrated!!

I have an IPhone 4. Heaps of apps are larger than apples restricted download limit. I made the mistake of upgrading an app, needing to delete it and trying to reinstall only to find that I have to connect to wifi. I don't have the luxury of wifi. I paid for the app so I'm furious. I'm not too keen on jail breaking. Any one have ideas to work around this..... Why is there a restriction?

Yes that's right - not everyone does, why do you (and obviously apple) assume so? I'm trying not to say anything as condescending as you have but it's getting difficult.
There doesn't seem to be any logical reason for this limit. I'm paying for the data I use so why does apple have a say in what apps I can download. It's a load of b****.
So thanks for stating the obvious. I know I'm not the only loyal iPhone user to have this problem so hopefully someone clever at apple will pay attention and make some changes soon.

HT3209 If i buy a standar definition movie on iTunes, can I download the HD version later for a lower price? Can I download the other vertions (I mean in language and stuff) for free or a lower prize?

I just want to know if by purchasing a movie on iTunes, can I download other vertions of the same movie? Like subtitle editions and other language editions or get a lower prize when purchasing the same movie in a higher definition... Etc?

No. To purchase other versions of movies on the iTunes Store you'll have to pay full price for those versions. The content owners control this licensing and pricing to a large extent.

Every time I try to download a free or paid app or in iTunes it asks me for a credit card. (Which i don't have one) How can i download free apps without a credit card and not reset my apple ID? I already put in 20$!!!!!

If None is not available - On your computer launch iTunes and click "iTunes Store" in the left navigation pane. Click the "down arrow" next to your name at the top right side of the page and click "Account." Enter your username and password and click "View Account" to log into your account information. Next to your Payment Type, click "Edit." Select the "None" button and click "Done." Confirm that your card has been removed by returning to the Apple account information screen.

See if a reset works?
Press and hold the Sleep/Wake button and the Home button together for at least ten seconds, until the Apple logo appears.

My iPhone 3S will not allow me to upgrade. I can't download any apps and when I connected my iPhone to iTunes and tried to upgrade it, it said it was already updated. On top of that, WiFi does not work with my iPhone. What do I do to fix this?

My dad got this iPhone for me a few months ago as a gift since I had a really awful phone before. The only thing is, I can't seem to upgrade it to the latest software without it telling me it's already updated to iOS 4 or something like that. (I would be able to give you the exact iOS version, but ever since connecting my iPhone to iTunes, my phone isn't responding so I can't check the settings or anything.) I can't download any apps (I get an error message saying the software on my phone is too old) and so I pretty much am extremely limited to what I can do on this phone. I'm very frustrated at this point and incredibly displeased with Apple's products.
If someone could please explain to me why this is happening and what I can do to fix it, I'd be extremely grateful.
Thanks.

What iPhone do you have? You can check in settings>>general>> about.
If you have a 3G you cannot update beyond iOS 4.2.1. The 3G is over 4 years old an was discontinued over 2 1/2 years ago. You need the latest ios to run the latest versions of some apps. If you have a 3GS you can update.
If your phone is not responding, reset it by pressing and holding down both the home button ad lock/ sleep button simultaneously until the Apple logo appears.

Itunes won;t open and can't download new apps

Hi guys,
I've got a huge problem and I hope I can solve it here. I ve got an ipod touch for smth like 2 months and all of sudden, when i connect it to the PC , itunes isn't starting automatically and i have to do it manually, even though until now it did open automatically. Also, a bigger problem is that I can't download new apps and i can;t update the ones i already have... when i try to do it, it just shows the sign of "waiting" and it frozes like this, so i can't use the app anymore... i tried to reset all settings, to reset the network settings, i searched for a lot of answers on the internet, but my problem wasn;t solved. So, if u can please tell me what should I do, considering that i haven;t tried to erase all content and settings and also my itunes is up to date. If i missed a detail you want to know, let me know, i ll answer, but i hope i wrote everything thatwould be useful in giving me an answer. Thank you!!

I had a similar problem and ran across this old post from ilounge. I am running Win 7 and lost my playlists to the new upgrade. Then my old ipod died before I could hook it up. When I followed this insruction it restored all my songs and playlists (so there was duplication but I got everything back). Might work for you.

I'm running windows XP and seem to have found a partial solution that does not involve vague half assed directions =P
Open iTunes, go to file, import, and select the latest "Temp" file, I got most of my playlists and songs back that way.
Edit: This file is in the \My Documents\My Music\iTunes folder

HT1657 Once a rented movie is downloaded do I need an Internet connection to view it? For example can I download a movie and watch it on a flight?

Once a rented movie is downloaded do I need an Internet connection to view it? For example can I download a movie and watch it on a flight?

Please be aware of the movie rental's time limitation that you have 30 days from the time of rental to watch your movie, and once you start watching it, you have 24 hours to finish watching it. You may watch it as many times as you like during those 24 hours. It may be helpful to make sure the download completes successfully before you begin watching the movie.
Once the download is complete you can watch it without an Internet connection. However, an Internet connection to the iTunes Store is required to authorize playback or activate the 24 hours time-limit of movie rentals. This means, only during the starting of the movie. Once you have started playing the movie rental, internet connection is not required. You can play anywhere without internet connection.
For more information on movie rentals, you can visit:

Note: 24 hours time limit is for United States customer only, while 48 hours for other countries.

We have 150 iPads at our school. What effective ways have you found to update and download new apps to such a large number of iPads? Can I download different apps to different sub sets of our large group - or must they all have the same apps?

At our elementary school, our 150 iPads are separated into 5 subsets. Can I download different apps to each subset, or must they all have the same apps since they all share the same Apple ID. Some iPads are for grades k-2, and some are for 3-5. I'd like to have the best apps for the different grade levels on the iPads. Currently we have "iPad Carts" to house our iPads in, and could use them to upload and update apps all at once, but don't utilize this function as we have a custom set up for the iPads that is erased each time we update through the carts.

You can configure different set of apps for different groups of ipads.
You need an mdm to do this.

HT201303 I forgot the security answers for my App Store account and I can't download any apps on my new apple device

I can't download any apps on my new i device because I forgot the security question answers. How to I get the answers back? Help plz

Reset Security Questions
Frequently asked questions about Apple ID
Manage My Apple ID
Or you can email iTunes Support at iTunes Store Support.
If all else fails:
1. Go to: Apple Express Lane;
2. Under Product Categories choose iTunes;
3. Then choose iTunes Store;
4. Then choose Account Management;
5. Now choose iTunes Store Security and answer the bullet questions, then click
      Continue;
6. Sign in with your Apple ID and press Continue;
7. Under Contact Options fill out the information and advise iTunes that you would
      like your security/challenge questions reset;
8. Click Send/Continue.
You should get a response within 24 hours by email.
In the event you are unsuccessful then contact AppleCare - Contacting Apple for support and service.
Another user had success doing the following:
I got some help from an apple assistant on the phone. It is kind of round about way to get in.
Here is what he said to do and it is working for me...
a. on the device that is asking you for the security questions go to "settings", > "store" >
      tap the Apple ID and choose view"Apple ID" and sign in.
b. Tap on payment information and add a credit/debit card of your preference then select
      "done", in the upper right corner
c. sign out and back into iTunes on the device by going to "settings"> "store" > tap the
      Apple ID and choose "sign-out" > Tap "sign -in" > "use existing Apple ID" and you
      should be asked to verify your security code for the credit /debit card and NOT the
      security questions.
d. At this time you can remove the card by going back in to edit the payment info and
      selecting "none" as the card type then saving the changes by selecting "done". You
      should now be able to use your iTunes store credit without answering the security
      questions.
It's working for me ...I just have to put in my 3 digit security pin from the credit card I am using.
Good Luck friends!

I believe songs purchased in iTunes can be downloaded to a max of 5 devices. Does this count include the unregistered devices.

I believe songs purchased in iTunes can be downloaded to a max of 5 devices. Does this count include the unregistered devices. ie. If I have already registered and downloaded music on 5 devices and now If I unregister one of the older device, can I go ahead and download songs in a new device ?

You can have a maximum of 5 computers authorized to play DRM-restricted content purchased from the iTunes Store. You can have a maximum of 10 devices (computers and iOS) associated to your Apple ID.
However, since all music sold on the iTunes Store has been DRM-free since late 2009 there is no longer a number of devices restriction for music. It is possible to sync, via USB or Wi Fi, an unlimited number of iOS devices.

I've got it working on mine by downloading the old facebook app version 4.0.1 from the following link. In iTunes, go to file menu, select add file to library and add the downloaded ipa file and facebook will appear in the apps screen. next sync will then put facebook on your iphone 3G.
