With a first generation iPhone or an iPhone 3G, you only have 128 MB of memory. The iPhone’s internet browser Safari takes up a big portion of that memory. And that portion keeps growing if you open up more pages. If you have a jailbroken device you can force apps to close via SBSettings. But wouldn’t it be handy to close Safari automatically after you press the homebutton? Cydia has an answer.
Go to Cydia and add the following source: cydia.iphoneil.net. After that search for install SafariQuitter. Once SafariQuitter is installed, respring your iPhone (or iPod Touch) and you are good to go.
It will probably free up to 20 MB of memory. A major change and the chance that other apps (mostly games) crash will be significantly lower.
