I have an iPhone 3G 16GB (4.3.5 version) more than a year I have used this device, but now it has become slow when opening apps and slide is frequently late, just like is in the process or something.
What is the best solution to solve the problem of slow iPhone ?
Try restoring your system back to normal. It usually solves all the problems regarding iPhone, iPod, and iTouch when its becoming slow on opening files or apps. To do this, you must have ITunes installed on your computer. Then plug in your device, and look for the restore settings button. These will also format your current system and all files in your memory will be erased. So make sure to make a backup first.
Note: Make sure that the restoration will not be interrupted or else, you might even face a bigger problem. There is a big chance that your device will no longer works if the restoration is stopped suddenly.
