Hi, hopefully someone can help. I have a T-mobile mytouch 4g, recently apps on my phone do not show up in my app drawer. In the beginning after rebooting the phone worked...and then I would have to go through a few different variations of shutting down the phone, taking out and then re-inserting the SD card to get it recognized and now none of that works. If I put the SD card in a media reader I can view everything on the computer. One strange thing is that I can view and play music on my phones media room. If I go into settings > manage applications it doesn't show anything under my SD card. My phones not rooted or anything. I took the phone to factory defaults thinking that would help and it hasn't. This is my first smartphone and I'm freaking out because even when I go to the android market to download or even update apps, nothing happens. Does anyone have a fix for this? I'm using Android version 2.2.1...do I need to upgrade??? Please help
