iPhone 3.0 allows you to search for applications, contacts, mail and a lot more with Spotlight on iPhone. It can be accessed by pressing the Home button when you are on the Home/First screen. It will start searching as soon as you start to type. Apart from keeping the most frequently accessed applications on the Home screen, one other way to quickly access your favorite apps is by using Spotlight search.If you have a set of apps which are starting with common characters like “Ph” then you can just type “Ph” in search. As long as you do not press cancel, this list is available to you. This is persistent even if you lock the screen, do something else and then again go to search. This will help you to access your apps quickly and efficiently provided they have some characters in common.iPhone 3.0 update is available today.Update: Since there seemed to be some confusion regarding this, I would like to clarify. I am talking about putting the last search in Spotlight to use for accessing most frequently used apps. Say, you have N number of frequently accessed apps. There are two ways to access them frequently:1. You can move the icons of the apps to Home screen or closer to Home screen (on second or third screen).2. You can search them individually with Spotlight.Now, since all of them cannot fit into the Home page what you can do is - you can find the common characters in those 20 apps. For example, lets say that my most frequently used apps apart from those on the Home screen have “Ph” as the common character. So, what I would do is rather than having to flick and find them or find the app individually by typing “Phone Aid” - I would type “Ph” in the Spotlight search and keep it that way. I would not press the cancel button. This way you have access to your frequently used app (with particular characters) by pressing Home + Home button.Over a period of time, your frequently used apps change. Currently, there is no way to organize apps by most frequently used in iTunes or iPhone. So, rather than bringing all the apps closer to Home screen, you can just find the common characters within them (if they have any) and not press cancel on Spotlight so as to keep it persistent. Lets say now my most frequently accessed apps begin with “F”, I can type F and not press cancel.BTW, Spotlight also stores the scroll state for the search. So say you type “F” but the first 2 apps showing on the result are not important to you, you can adjust the scroll view so that the first two apps are out of the view. You can make your phone calls, go to home screen to access your apps and then if you again come back to the Spotlight screen, the scroll state would still show the results with “F” minus the first 2 apps that are out of the view. This way you always have access to your frequently used apps by pressing Home + Home. Hope that this helps.
