Hello, I have been successfully downloading OTA the same jad/jar binaries to my Sanyo PRO-700 and Sanyo 7050 for months, and as of yesterday I am now receiveing the infamous "Data Error 909, Application Authentication Failure" on both of these phones. This issue came to my attention from a customer trying to download the app, and then i was able to reproduce it.

Is anyone having recent issues with the 909 error? Any thoughts? Thanks.

are these signed with the sprint developer's tool? if so, i think the certificate used to do the signing expired around the end of october.

Rusty, yes, the app was signed using the Sprint Wireless Toolkit. Do you know how I can resolve this problem? Thanks.

we have been told by sprint they are "working" on the problem. it seems like it should be something relatively easy for sprint to fix (and they should have seen it coming).

there is a method to sign the app with your own certificate, but i don't know exactly what is involved with that.

Have you switched your phone to developer mode?

a new certificate appears to be available here:

http://developer.sprint.com/site/global/develop/mo bile_platforms/java_me/javame.jsp

look under SDK&Dev tools

also, if you use eclipse for development, now that you have the password you can set it up to sign the application for you automatically, the only thing you need to know is the alias that is "sprintadp"

A known issue with the Sun WTK 2.5 (the underlying software for the Sprint WTK 3.3.2) is causing issues with digital signing with the new developer cert. We are working on a update to the keystore used for code signing to resolve the problem but until this fix is made available you can use the current keystore (available under the SDK & Tools tab in the Java ME section on the ADP website) to sign your applications using the Sprint WTK 3.3.2 and then remove the line that contatins the MIDlet-Certificate-1-3 and the cert. This should make your developer signed app downaload on a developer mode enabled handset.

Thanks
Sprint ADP
