I know some of you guys have an iPhone 3G (like myself), and I know that the 3G is pretty slow, when running the iOS 4. Here are some steps to make your iPhone 3G faster. Step 1: Open Safari and close ALL opened web pages. When you have a lot of pages opened, the iPhone becomes slower, since it uses more RAM memory to keep those pages opened all the time. Step 2: Go to Setting->General->Home Button->Spotlight search and uncheck everything. By doing this you turn off Spotlight search, and the iPhone will run a bit faster. DON'T forget to reboot your iPhone after doing this. Step 3: The iPhone 3G does have some sort of multitasking. This means that even tough you quit and app, the iPhone doesn't completely close the app.To close ALL apps running, Hold down the Sleep/Wake button until the "Slide to power off" slide appears. Now hold the Home Button for about 7 seconds, until the iPhone returns to the Home Screen.By doing this, the iPhone closes all apps that are running. Step 4: Don't forget to periodically Turn Off your iPhone. Don't keep it on for more than 2 days. Step 5: Enjoy your new iPhone 3G.
