When I read the HTC Desire user manual, it said that I need to turn on the "Data Connection" setting to have internet connection.
Well, this is understandable ... but, does it has automatic connection on demand?
On Windows Mobile, I dont have to specifically turn on data connection. Whenever an app is trying to reach the internet, it will turn on the data connection automatically.
And of course, it will turn-off the data connection automatically as well, when there is no internet network activity.
Does this also the same in Android?
It should turn on automaticly when you try to use online services...
But you can turn it on in Wireless & Network
You have to option to turn mobile data off, that is why it specifies that you need a data connection.
If you do not turn it off, apps that require internet access will use it with no further interaction.
By default MENU -> Settings -> Wireless & networks -> Mobile network was off on my device, meaning it would not connect to internet via 3G (I could still make/receive calls). However, I chose to use WiFi for set-up when I first started the phone, so maybe that's why.
Anyway, I guess that is the setting they are talking about.
Thanks for your information, but that raise a question:
When I switch off the data connection and also switch off the background data option.
Will the HTC Weather widget (and other similar widget) still work with auto-updating periodically?

NO... they need either 3G or WiFi connection to update...
So, that means ... those apps cannot wake up (turn-on) the data connection automatically if needed (on-demand) ...

I do remember the old days of the HTC Hero which had the option of background data usage. I think that was more to do with the version of Android than anything else. I recently had the Nexus One and on the new 2.1 version of Android, you can either switch data on or off, no automated connections on data usage.
When the phone is sleeping (screen off) nearly everything is powered down anyway, even if the data connection is 'on'. Apps will wake the device (an power up radios as required) to do their updates when they need to.

The whole idea of being able to turn your mobile data connection off is to disable mobile data completely. This is a very good option if you are roaming in a foreign country or don't have a fixed data plan.
If you leave the mobile data connection to enabled, applications will "turn-on" the data connection if needed (on-demand). In other words, if the mobile data connection is enabled, the mobile data connection will be in standby, waiting for applications to request use of the connection.
Hope this clarifies it for you, as you appeared to misunderstand my last post.
Ok then
I think it has different meaning compared to the Windows Mobile.
In the COMM MANAGER, there is "Data Connection" toggle which normally is OFF. And this does not mean that the device cannot use 3G data connection.
While on Android, its data connection toggle setting means to enable or disable 3G data connection completely.
I think that is the difference, if we look from Windows Mobile point of view.
Thanks.

I've stumbled on a strange issue.
If I switch the Desire to the Airplan mode when the Data connection is off (I use the appropriate HTC Data connection widget to do this), when I switch back to Airplan mode off, the phone is no more able to restore the data connection.
The only workaround found is to restart the phone.
Has anyone got the same experience?
Two questions.
1. When you say you switched off data connection, are you talking about syncing, wifi, mobile network, ... etc?
2. Why do you want to switch off data connection and turn on Airplane Mode? Doesn't Airplane Mode cater for shutting down all wireless?
1. I'm talking only about the "Data connection" option on "Wireless and networks" menu, that is switchable via a special HTC widget. Switching this option off, the phone is no more able to access to the GPRS provider. I often keep this option off to save battery life. I turn Data connection on, if I need to sync and access to Internet.
2. This is not the matter, just it happens. Eg. When I go to sleep, I turn the Airplane mode on, doesn't matter if the Data connection is on or off (it is possible that it is on) in order to avoid any disturbs (calls, sms, etc.).
I just wonder if this issue is a true bug of the phone:
1. Switch off Data connection
2. Switch on Airplane mode
3. Switch off Airlplane mode
4. Try to activate Data connection (for me it seems it's not possible without a reboot)
Had a similar problem which I wrote to HTC about: after the phone has been data connected via wifi and I leave the wifi network it often will not connect to data via mobile network (GPRS/3G), giving the message "connection failed" if I try to manually connect in the "mobile networks" section of the "wireless & networks" settings page.
It seems to have fixed itself now, and I think it's because I've since ticked the option to "enable always-on mobile data", which I had turned off to save battery. Give it a try.

Thanks yurikg, but on my phone the "enable always-on mobile data" option is checked, anche there is no mobile network connection problem coming back from a Wifi connection.
The problem I shown is probably caused coming back from Airplane mode.
The other possibility is Juicedefender which apparently is known to cause problems recovering a mobile data connection (recent update may have fixed this):

I've not juicedefender on my Desire...
I've in plan to do some other tests...
I have a problem with my Desire reconnecting to a mobile data connection too, but not when I come out of 'plane mode, its when I leave a Wifi covered area. It could be the same problem, triggered by anything that disables and then reactivates the data connection?
I have no solution yet, and I have contacted HTC support about it (still no reply). There is some discussion here:
http://forum.xda-developers.com/showthread.php?t=656192
I seem to be having this problem too when coming off WiFi connection, unfortunately restarting the phone has not righted the issue...
I'm also having this problem with the connections. Fine on the wifi at work and at home but not switching over to the mobile network. Apart from that the phone seems awesome! Soooooo much better and more fun than the HD2.
OK, my phone appears to have no network connection whatsoever in fact...
Have the same problem as well. Coming from Wifi and to mobile network only - I do not get any data coverage. This is for the Desire and I had the same problem with Legend.
I hope this will be worked out ASAP.
Well, my problems all sorted. Turns out I had to manually input the APN for internet, took me by surprise since no phone I've owned since 2006 has needed that...
Just had to put in the settings manually too. Seems there is an issue with some of them. Would put a link here but as i'm a newbie not allowed Just google vodafone apn settings for htc desire and hey presto
Same problem here, my Hero had it too. I found it did work when you switch to gsm only and back to 3g/gsm... Would love to hear good solutions.
Im also having the same problem.
If i try switching my connection from wifi to mobile data, my mobile data connection fails to work. A power cycle fixes the issue but if i try switching connections again, the problem returns.
Can I suggest to anyone still having problems getting their phone to switch to mobile data when leaving Wifi to view the following bug report on Google Code and to star it to help raise the priority with Google:

Thanks folks
It's been a month or so since my phone started to have problems with mobile data connection. It's most of the time offline, even if i set mobile data on; when i try to connecto to mobile data, it takes some tries to resume connection. I've also noticed that mobile data connection goes off when making or receiving calls. I've tried several different combinations of roms and radios with no success, and now i really don't know what to do. Any suggestions?
My mobile data doesn't always turn off when wifi is on. Any ideas?
detour http://forum.xda-developers.com/showthread.php?t=1313800
Not quite sure when this happened, but it seems like whenever I disconnect from Wifi now, my mobile data does not automatically enable. I tried downloading a data widget to force it on, but that doesn't work. I either have to restart the phone, or toggle airplane mode to get my 4G back. Anyone else have this issue?
Is there any way to force a hard connect on the mobile data?
