Background data usage: what draws data when you're not looking?

I have "Fetch New Data" turned off; and I have Wi-Fi at home; and I don't use the 3G connection that much during my work day for fear of cracking my fairly small 250Mb cap. I track it reasonable closely on the iPhone, and in any case I can download my carrier's day by day figures as an extra check.
And so on average I only get through about 2Mb per day on 3G as measured by my carrier (I find the iPhone tends to underestimate it slightly).
+Until yesterday.+ I didn't use the iPhone any obviously different way, but my carrier says I used +180Mb during the day+. And even weirder, the iPhone thinks I used around 340Mb yesterday (so clearly my carrier cannot be completely wrong).
Now I have some overage fees to pay (about US$50) and I'll have to stop using 3G until the billing cycle ends (luckily just three days away)
Anyone experienced anything like this before?
Anyone know what may have caused it?
For example, could Mobile Safari be stuck on an auto-refreshing page and consuming data in the background?

I think you are on to it with the self refreshing idea. I am an American user, so our data plan is a little different. We pay a flat 30 dollars extra each month for unlimited data, so nobody tracks usage. But I do know that safari updates mobile pages every 15 seconds on some sites(espn,nfl etc). I would suggest resetting the phone to ensure your safari isn't keeping a page open. You should also look for any apps you have added that may be auto refreshing, weather and sports apps are the most notorious. Good Luck.
I actually checked my Safari history... and there's nothing for that whole day. On the other hand, I'm pretty sure I did surf some pages that day, so that's a bit screwy in itself.
I'm going to try and see if the carrier can pull some logs from somewhere. It's a long shot...

HT1212 What to do when you have not synced to itunes and when it says to connect to itunes?

what to do when you have not synced to itunes and when your ipod says connect to itunes?

Disabled
Place the iOS device in Recovery Mode and then connect to your computer and restore via iTunes. The iPod will be erased.
iOS: Wrong passcode results in red disabled screen
If recovery mode does not work try DFU mode.

For how to restore:
iTunes: Restoring iOS software
To restore from backup see:
iOS: How to back up
If you restore from iCloud backup the apps will be automatically downloaded. If you restore from iTunes backup the apps and music have to be in the iTunes library since synced media like apps and music are not included in the backup of the iOS device that iTunes makes.
You can redownload most iTunes purchases by:
Downloading past purchases from the App Store, iBookstore, and iTunes Store

How to decrypt data when you can't get the private key in Windows?

I'm very confuse. My english is poor, but I try to say my question clearly.
When browser connects to a https website which needs client certificate to authenticate the identity, the browser will send client certificate to web server.
Then the web server will use the certificate to encrypt some data and send it to browser.
Then broswer should have private key to decrypt that.
But as I know, if I install a pfx format personal certificate, I can set can't export private key, which means you can't get the private key to use it. So how can
the browser decrypt the data without private key?
By the way, what is CSP, use CSP's interface can we use CryptoAPI
to decrypt data without private key?

Answer for question is "you cant"..

I purchased an unlocked iPhone4 last month. Everything was fine till yesterday. Today morning when I tried to check mail, i suddenly got an error message saying " Could not activate cellular data network: you are not subscribed to a cellular data service"

I purchased an unlocked iPhone4 last month. Everything was fine till yesterday. Today morning when I tried to check mail, i suddenly got an error message saying " Could not activate cellular data network: you are not subscribed to a cellular data service", when I checked on my network settings i was not able to find the cellular data network tab ( where we use to input APN manually). i even tried to restore my iPhone to its factory settings, Still it remains the same. i cant able to connect to Internet using cellular data. help me...Plz..

Where did you purchase it from? There are lots of iPhones sold as "unlocked" which are carrier locked phones that were hacked and are not officially unlocked. These phones are subject to re-locking to the original carrier, particularly when updated.

TS1702 What to do when you get "iTunes library app not installed on iPhone; app could not be found"

What to do when you get "iTunes library app not installed on iPhone; app could not be found". None of the Apple suggestions fix the problem. For example, with Animoto, one of the problem apps, I have removed it, reinstalled it, and still get the eoor message.

Of course.
First of all, this started when an external drive i was using died on me. I have no doubt that these apps indeed are off my system. I figure between the apps I've bought for myself and my kid, I have about 150 apps.
Now. The issue.
When I sync my iPad with iTunes on my desktop, it goes through normally until it gets to the apps. When that happens, it get an error box that reads "Some of the apps in your iTunes library were not installed on the iPad because one or more errors occurred. For a list of appps that could not be installed, click on the triangle below."
Then I get a list of apps.
(Added note to any iTunes developers out there: The titles of the apps in this list do not always match the titles of the apps in the App Store. For example, one was called "MuseumGame" on my iPad. It's called "Museum of Thieves" on the App Store. I started out with a list of 60 apps. It was a major pain to track them all down. It would be nice to have everything the same so I can use the App Store search more effectively.)
Anyway, moving on....
The error message stops my sync until I dismiss it. That, honestly, is what makes this whole thing annoying enough to seek out an answer. I can't let my iPad start syncing and walk out of the room. Yeah. I know. First World problems.
Once I dismiss the error, the sync continues and all is well.
I did the following to try to fix the problem. Mostly, I did a lot of searches:
My list of purchased apps on my iPad both using the search box and by going to every page
Searched the main App Store on my iPad using the search field. When that didn't work, I used wider searches and just scanned the page(s) for the little cloud icon that showed I had purchased the app.
I got on my desktop iTunes and searched the apps from there (without a lot of hope, but trying to be complete)
At that point, I came to the conclusion that a small number of the apps are no longer available on the App Store.
Fine. I didn't want them anyway.
I got into iTunes and went to the Apps page. None of the errant apps showed up there. I searched the iTunes help files. Nothing. I crossed my fingers, said a little prayer to the search engine gods, and tried Google. I found some things that sort of matched but they basically boiled down to "re-download the app from the App Store" or "Restore your iPad".
So I spent a couple of hours restoring my iPad. I got the error message again. I hit Google again and came up with this thread. It was as close to my problem as I found.
I think that brings us up to date.
My fundamental problem is that I seem to have found a scenario where if you have to restore apps (because, perhaps, your external drive died) and some of the apps are no longer available for download, there is an error generated that can not be permanently dismissed.
Did I miss anything important?

HI, I need your help. How can I delete all data, when I do not have the special security code, which I didn´t remember ? I also think, that I never create this code before. But I cannot put my settings back.

You must remember the code, if you can't then take the phone and proof of purchase to an Apple Store.

HT201299 How do I use my cellular Data when I am not at home? ( at the Gym, etc)

How do I connect to My cellular Data when I am not at home, ( gym) etc?

You normally don't need to do anything special. Your iPhone should always be connected to the cell network unless you're in a building that blocks connection to your cell carrier's network, or you connect your phone to a Wi-Fi network. Are you having problems of some kind?

Cannot activate cellular data network you are not subscribed to

Cannot activate cellular data network you are not subscribed to a cellular data service. Never happened until I have switched to boost. I have spoken with them for hours and they say it's fine from their end and I've reset network settings, replaced my nano sim for my iPhone 5, restored my phone played with wifi on and off airplane mode on and off I don't know what else I can do. Please help me experts!

Under "settings / general / network" is your "Cellular Data" button set to "ON"?

What to do when you encounter "does not have the proper security settings

What to do when you encounter: /Library/StartupItems/Qmaster" has not been started because it does not have the proper security settings. AND......../Startup Parameters.Plist ?
I have a PowerMac G5 using Operating system 10.6.8
I took this mac to the Apple store, they reset my os software and I have been having problems eversince. Since this Mac weights about 50 lbs, I don't want to take it in a gain. But - I am 67 years old and don't really understand some lingo - so straight english would really help.
I so appreciate any help I can get.

>>I have no idea what all that means...
rwxrwxrwx root admin
It shows that the files are owned by 'root' & in the group 'admin', while being readable (r) , writeable (w) & executable (x) by user:root, group:admin and everyone else.
Startup items must be owned by root, the group must be wheel, and they must only be writeable by root.
You can't readily make the required changes via Finder, so you'll either need to reinstall the software that added them, remove (trash) them altogether (they start qmaster, used by fcp &/or compressor) or use Terminal & the 'sudo' command to alter the ownership & permissions.
If you choose the latter - run these two commands in Terminal while using an admin account, you'll be asked to enter the admin password, which won't be echoed onscreen. Restart afterwards. It's important that you copy/paste these exactly.
sudo chown -R root:wheel /Library/Startupitems
sudo chmod -R ugo+rwX,go-w /Library/Startupitems
However - your startup problems with the prohibited sign are unlikely to be resolved by this, although it should avoid the warning messages you describe.
When did the startup problems begin - after adding any new software or making other changes ?.

What's lost when you reconfigure Enterprise Manager?

Hi all,
Going straight into the questions:
What's lost when you reconfigure a EM? And,
What's stored in the EM Repository?
Configuration: Windows 2003 Server Enterprise, Oracle 10g release 2
All of the EM consoles stopped working after we changed the host name on a Windows Server. The EMC services refuse to start.
It seems that using emca to reconfigure the EMs fixes the problem. But the other problem is that EMCA mentioned that all configuration would be lost.
I tried searching around the forum, Google and the official documentation but couldn't find much details.
It would be much appreciated if you could help me out a bit.
Thanks,
Benjamin

EM repository consists set of tables in a database containing state information for the managed environment and information about the management packs. It is used as a back-end store by the Oracle Management Servers, providing distributed control between clients and managed nodes.
