My partner has her Desire set to download/sync emails once a day but, it's downloading them more than that once a day. Is there perhaps another setting we're missing, or another setting which tells it how often to sync? It's set to once a day but, went off twice while we were at her mums yesterday within, id say an hour but, I think it was more like half an hour. It also notified her of more emails later on....I heard it go off about 5am this morning, to be told it was the fifth time it'd done it and so now it was on airplane mode which wasnt convenient. I managed to turn off syncing altogether (facebook gave me an option to change frequency, email didnt so i had to turn it all off in the menu i was in), which isnt convenient as she wants the weather to be updated regularly - Also an option on the list (cant remember what the third one was but, four options in total). So I'm thinking there must be somewhere else which says how frequently to update.
