I have a J2ME application that I sign with a Verisign Class 3 Digital certificate
(trusted 3rd party domain) and it installs and works fine on my Nokia 6230i but
when I install it on my Nokia 6270 and try and execute the application I receive
an "Invalid Application" error and then it asks me if I want to delete the
application. I have tried changing the permissions attributes in the jad file with
no luck. I assume that if there was a problem with the actual signing process
then the 6270 should not have allowed the installation in the first place. Has
anyone seen this error on any series 40 3rd edition device? Here is the
permissions attributes from the jad file:

MIDlet-Permissions: javax.microedition.io.Connector.http,javax.microedition.io.Connector.datagram,javax.microedition.io.Connector.datagramreceiver,javax.microedition.io.PushRegistry,javax.wireless.messaging.sms.receive,javax.wireless.messaging.sms.send,javax.microedition.io.Connector.sms,javax.microedition.io.Connector.file.read,javax.microedition.io.Connector.file.write
