I have a few questions for the more experienced Desire users. Is there any point having GPS on all the time? Or would it be easier on the battery if I switched it off? Is there any point having auto-sync and background data on all the time? If I switch off auto-sync and background data, does this mean I will not get the notifications from Facebook on the drag down menu and other similar things? What are the differences between the Facebook Android App and FacebookTouch internet website? I assume the touch website is just a website suitable for touchscreen handsets and devices? When I get Facebook notifications via the Android App, I am sometimes taken to the touch internet website. Is there any way you can access your inbox and events via the Android app? I haven't found a way to do this yet. In message settings, I think there is an option for Roaming auto-retrieve. Should I have this ticked or not? Am I right in thinking it just means it will automatically retrieve MMS messages? This will be free while in the UK and using my free internet from T-Mobile, won't it? I think that's it for now! I'm sure I'll think of more later! I'm really liking the phone though, even if I haven't used it to its full potential yet (customisation etc) as I probably will be getting it replaced due to the speck of dust under the screen.
