iOS 4.3 has cut my 3G Internet connection

SAME PROBLEM HERE IN GERMANY WITH VODAFONE-MOBILCOM-SIM!
Hard to get a working 3g-connection AFTER updating to 4.3 and then freezings/rebootings.
If sim-action is switched off, the ipad works fine....
So APPLE do something!
Could be very interesting for iPad 2 3g, which comes also with the stupid 4.3-firmware!
Things like these should not happened!

My 3G is gone also. Even with full signal, i get a mix or error messages such as not subscribing to a data service. I called my provider, 3 (3.dk), and checked my configuration as well as my account and everything seemed to be ok. This is really annoying.

After the update to 4.3 experienced the same issues as read by you all world wide. In my case it is Vodafone provider which informed me that many users of IPAD as well as IPHONE in The Netherlands experience this issue. No access possible and many more issues possible. Reset did not work either. The only thing to do is to take out the SIM card and it is working with WiFi.
Vodafone Netherlands informed that Apple has confirmed that there is a software bug on the new released OS4.3 and that they are working on this matter. When a new release will take place is so far not known.
Vodafone The Netherlands and many of its operators have tried out many ways to overcome this matter but could not find a solution. It is thus awaiting at Apple its update. I think and reading on the forum that not only Vodafone has this issue, but many more it is basicaaly confirmed that it is a bug in the software new release of Apple. Please contact apple for this as much as possible for swift solutions, thanks Jan

I'm in France and experience the same problem, I lost me 3G connexion after updating my Ipad to iOS 4.3; My son managed (after several attempts) to update his iphone 4 and has no problem with his 3G connexion though we have the same carrier.Perhaps it's only for ipad...
Did someone find a solution? If i don't have 3G I have no access to Internet.
If the problem is on Apple's side, we urgently need an update to fix this bug

Hi, I got the same problem here in Mexico, I permanently fixed this problem (sorry for my bad English I just want to help)

1.- turn on your wifi and mobile data (both requires Internet connection)
2.- open safari
3.- load any web page (Facebook, google, etc)
4.- go back to setting and turn of your wifi
5.- as you can see now the iPad detects the 3G connection on safari or mail

Note: every time you turn off your mobile data, you have to do the steps above.
Obviously this is an iOS 4.3 bug, and this issue should be fixed ASAP

Rod's Workaround affirms my experience.

Additionally, you can put your iPad to sleep and wake it up and the connection is still working. Switching off your 3G interface require the same procedure as described by Rod.

Same problem, same workaround.
Rod, thank you.
Apple, please fix.

These Steps does not work for me and I am not able to use internet on my iPAD version 1 anymore after upgrading to iOS 4.3.

Not sure what else can be done? Will Apple Fix this issue?

Same Problem Here in Thailand with TOT3G, could not active cellular data, no internet connection, can occure even full cellular signal from operator.
sometime have to wait half an hour.
Please fix it.

Hi i'm from malaysia, after Upgrade to IOS4.3 cellular network from Maxis just won't work when browsing using safari, something wrong with the 4.3, APPLE pls fix this ASAP ..... very annoying

Same problem here in the UK using 3 network. Seems to happen when my iPad looses 3G signal (going through a tunnel on the train for example) I then have to switch airplane mode on and off a few times to get a connection again despite it showing full 3G bars

Same happens in Vodafone PT. First login recognizes network, but while acessing email or Safari, it returns no 3G available (signal almost in full).

Disabling 3G and enabling it back, often solves the problem, although it often does not ask network PIN while logging in!

Before upgrade never faced this kid of issue!

CIao a tutti. I have the same problem after upgrade it.
Safari cannot open This page because you are not connected to the internet!
I spoke to Vodafone and they told me that line is ok.
I dont know what to do it now

If any of you haven't tried the suggested workaround by Rod_011001 above, it's worth trying. It seems to have worked for at least 3 of us, though not everyone. Might only work if you are in the presence of a WiFi network that you are able to log into, don't know.

I have the same problem, provider bob.at in Austria. I think the problem has nothing to do with any provider it's definitely an iOS 4.3 bug associated with first generation iPads. When wlan is switched off when you deactivate the airplane modus you get problems with 3G. When wlan is switched on when you deactivate the airplane modus 3G works, even if you switch off WLAN immediately afterwards.
Basically I have the feeling that 3G is less reliable with iOS 4.3 even when you got it up.
