I have a new droid eris and am having a few issues with the phone.
1. It doesn't call who I select, but someone random.
2. It makes calls that I do not intend to make, ie it randomly calls people without my knowledge.
This is happening with both mine and my husbands phone.
Also is there a way to lock your phone with a short cut key.
Yes go in the market and in the search box type: Call Confirm
Download and install it will solve your problem.
To lock your phone press the Red highlighted silver end button on your lower right on your phone.
