Does anyone elses X suck since the upgrade? I loved this phone before, but I am starting to really dislike it now. It seems like everything lags now, no matter what is opening or closing. Even deleting e-mails takes substanitally longer. The other major complaint I have is if I download any type of document from the internet, I get a quick flash of the last document viewed whenever I open or close the browser. This lasts until I restart the phone. I am experiencing normal issues?
