I've had a problem on my 3GS, since I got it in June. The problem is, sometimes, when I'm using Safari for example, black images or text at the top of the screen turn green. Again, it isn't always this way, but a good portion of time. One thing that I often notice it on, when it's happening, is in Safari above the website address where the title of the page is, such as "untitled," if it's blank. Sometimes the text there is green instead of black. And I've seen this when the web page had some black content towards the top. Any ideas? Anyone else seen this from time to time on their phone? Thanks.
