Hi again,
Before even trying this..does T+ update weather/news info through GPRS connection to web?. Or does it only do it through ActiveSync.
It is able to update date when you have an internet connection active. It doesn't matter if its GPRS or ActiveSync passthrough.
The only difference is the automatic refresh (if that's what you meant)
Using GPRS (not using ActiveSync) it will not try to sync automatically, so you have to manually press the refresh button (if the skin you're using has one)
I sync a lot using GPRS dialup and works great :)
