I have an HTC Incredible and have only had 2 days experience now with the android OS. I apologize for some of the questions that are about to follow, but I genuinely don't know. I have looked for youtube videos to 1) Apps vs widgets - what really is the difference? Widgets seem to sit actively on a homescreen, while apps are in the background and once you navigate away you must relaunch the app even though it is running in the background? 2) I have advanced task killer, but don't know what apps I need to routinely kill. For example I have Google talk and skype running. I think if I kill skype I will no longer be part of the conversations and won't receive events as they come in. Google talk I am not sure sure about. Since it is a native google product if I kill it, will I still get the messages as they happen? 3) How do you customize widgets? I can see from the various preloaded scenes that some of the widgets(?) can be different sizes and shapes. Favorites for instance in the work vs verizon scene is different. In the work scene is is only 1/2 of a homescreen, but in verizon default it is an entire homescreen. How do I choose the size? 4) WiFi - I simply can't get this to work. I have gone into my router and added the mac address, I have tried wep, no security, tried manual ip. Everything results in unable to obtain IP address. Again, sorry for sure elementary questions, I just didn't see anywhere on the android site that explained it and other research was equally fruitless.
