the one thing i did for that was use auto task killer, kill the app and play store. then i used settings widget and turned off my auto sync and network connection. wait a few minutes and turned it back on without auto sync, until i got it to work. and i restarted my phone once. if that doesnt work dial *228 and use programming in alot of cases its always worked. if you still have problems pm me cause im not always on this site.
