Okay, I've figured it out. For one reason or another, I was having problems with the browser. It would say, "html converter out of memory," or some other stupid message. So I would then restart the browser and lose all my net alerts. I know it's not the battery because I tried pulling it out while the phone was on but the alerts were still there. And my phone can't have old software because it's an i730. Also, I don't have the Go to feature or else I wouldn't be complaining. Yesterday I had to call my brother at home, tell him my sub-id, and send me an alert from teknidude.com.
On another note, would anybody happen to know why the html converter ran out of memory? Would it have anything to do with the 8 net alerts I had locked on my phone?
