I don't understand what is happening with my phone. I had a problem a while back that the apps i downloaded were working for maybe 2 days. Now the phone says that there all not installed on the phone. I didn't take out the SD card or change anything. But the weird part is that the only apps that disappeared were from the market. However there are only a few apps that stayed which i downloaded from the market. Its strange because some apps left and some stayed. Could someone please tell me why this is happening and how i can change it?
