I've downloaded a number of applications, including Monkeyball, Weatherbug and Enigmo, but when I press them I go to a loading screen for a few seconds and then and brought back to the home screen. I read on another forum of someone having a similar problem and they were able to solve it by turning their phone off and on; this solution did not work for me. I've downloaded a couple of other apps (AIM, iPhone Saber) which worked for me before but now the same thing is occurring. Has this happened to anyone else? Any ideas? Oh, I'm working with iPhone Classic with the obviously updated firmware.
