thanks a lot for the reply. I actually prefer if the WiFi is on all the time since I prefer to be online on my social networks (FB,Gtalk) even if my phone is on stand-by.

as for the feed, if I understood correctly what you said, I can set intervals for its updates after which when it does refresh, it pulls in stuff from my RSS, FB, Twitter etc? 10 minutes is fine, I just dont what to look at it and see it hasnt refreshed in 6 hours (something that was persistent in WP7 and it bothered me quite a lot)
