I have the latest version of the app on a non-jailbroken iPhone 4 running 4.3.1 and it STILL crashes constantly. And freezes. Is it so hard to make a nice app? Let the people from Echofon work on it. They've made a great Twitter app, that's for sure.hopefull convert m4v to wmv free can solve itStill slow and doesn't look like it will get any better. Thinking of getting Samsung Captivate. Can't afford an iPhone 4, but don't want to be forced by Apple to upgrade because of bad software. They should of left the 3G out of the upgrade cycle and everybody would be happy. Bad marketing Apple!
