<p>I am looking for an app that will let me type in code ON my cellphone. I don't need to compile or anything, and its not to program for the cellphone. Just something nice to have when an idea pops in my head.</p>

<p>Am I completely overlooking a simple code editor for Symbian S60v3 phones? </p>

<p>I am looking for something similar to <a href="http://www.logicalsky.com/Product_CEdit.php" rel="nofollow noreferrer">CEdit</a> which is for Windows Mobile. </p>
