Hey.. I have a problem with my Xperia X8. I rooted it because i wanted free apps. Anyways. I downloaded a apk. "Old or new market" So i tested it, and my main market is now gone. My phone is unrooted now. And i cant download any market from somewhere else because it just says it cant open package file. And when i try to reinstall the "packageinstaller" from system/app. It just says installing then it stops and i dont get a done message. So something seems to be wrong. Is it the root that did it or the program i mentioned before? I got market now. Veneding apk. But it just force close me everytime i go to market. Any ideas how to fix this?
