Okay so my phone will not intall or update certain apps, mostly games. The phone will download them but not be able to install, my brother has an Evo with the same hardware and the the same software and his installs the apps. Is anyone else having this problem. I am thinking about restoring phone to default setting to see if that would fix it but I don't want to have to go and reinstall all my apps that are working. Any suggestions on what to do?
