3GS mail sync in standby not using WIFI?!

[Snowjoggs]

Hi

I experienced a big jump in my phone bill after I recently got my 3GS.

After looking at the details on my bill it seems that it have charged me for data traffic for every mailsync I have done while my phone have been in standby mode, even though I have a active WLAN connection before my iPhone either goes into or is set to standby.

Am I correct in assuming 3GS does not support WLAN to be active in standby mode, and therefor it will always sync emails using normal cell 3G connection?

Wifi turns off in standby mode I believe yes... Do you not have a data plan at all? You should jailbreak and turn off 3G and Edge.
