How can I uninstall Alkido 1.1 when both Alkido 2.0 and Alkido 1.1 are installed on my Samsung Galaxy S
It sounds to me like Alkido 1.1 was bundled on your device as a system app.  To remove a system app, you need root.
There are two ways to address this easily, I would prefer #1 myself.
Method 1

Uninstall Alkido 2.0.
Install Titanium Backup.
Run Titanium and wait for it to load your app list.
Go to the app list and long-press on Alkido 1.1.
Choose &quot;Integrate with Market&quot; or similar.
Go to Settings -&gt; Applications -&gt; Manage applications, find the Market, and clear the data for it.
Open the Market, go to your apps, and update Alkido.

If that doesn't work or you don't want to bother keeping Alkido as a system app:
Method 2

Install Titanium.
Run Titanium, long-press on Alkido 1.1.
Choose &quot;Uninstall&quot; or similar.  You shouldn't need the &quot;hack&quot; version of uninstalling that it mentions, but you can try that if the regular uninstall doesn't work.

Alkido 2.0 will be unaffected if you didn't uninstall it in Method 1.
