I posted this on the lp forum, but I didn't get a single reply in 2 days. Here is my problem:
I decided to uninstall launcherpro for a day and run stock launcher to compare battery life. To my surprise I could not uninstall the application. Upon going to setting>applications>launcherpro I only got the option to "uninstall updates." I also tired to uninstall it through the market and I get the same problem. I decided to go ahead and hit "uninstall updates" to see what would happen. What happened after the uninstall was that inevitably upon hitting home I was asked which launcher I wanted to use, LP or stock. However, the launcherpro icon was now blue instead of the classic orange. Apparently the "uninstall updates" did just that (shocker) and I went to the classic version of LP. What is weird is that it does NOT show up in my applications list, nor in the market under the downloaded section.
I decided to try again and re installed LP from the market. This time I set my default launcher to stock tried to uninstall LP once again. Same issue. I could not uninstall the application, just the updates.
Anyone care to help?
