I have an iphone 3gs and I was feeling lucky when I upgraded it to iOS4. For some time I was enjoying this new OS but later I noticed a distinct slowdown in my iPhone since upgrading. My apps take longer to load, mail messages open slower, the whole system just feels more sluggish. Now I am in state of dilemma and do not know whether I should continue with it or degrade. If someone has any idea or know about it please tell me also
