I have my (lovely!) HTC Desire configured to use wifi only, since I don't have a data plan at the moment. My question is: will auto-sync try to connect using 3G?
For example, I'm happy to have my email, friend stream and such auto-sync every hour at home over wifi, but I don't it want to connect via 3G or EDGE when I go out.
Sorry if this is an obvious question, but I've searched and not found anything, and I'm scared of being landed with a huge bill if I get things wrong
Thanks in advance!
In the initial phone setup you are asked whether you want to connect to the internet via WiFi/3G or WiFi only - select the wifi only option. Not sure if tehre is an equivelent menu option if you've already set it up the other way, but imagine doing the following should prevent it from connecting to mobile data:
On home screen press hardware "Menu" button, then settings.
Choose "Wireless & networks"
Make sure the checkbox by "Mobile network" is NOT checked
Choose the menu option below - "Mobile networks"
Ensure that the checkbox besire "Enable always-on mobile data" is NOT checked.
I think that should do it. WiFi connection should still pull down the data, but it shouldn't try to connect to any 3G networks.
You'll be able to tell quickly - once it's up/downloading data on a mobile network there is a symbol on the notification bar beside the signal strength representing which connection you are on (2G, 3G, H for HSDPA etc.) with an up and down arrow beneath it that flash when data is active. None of these are here when not connected to a data network (much like when you're on WiFi, these mobile data symbols don't appear).
