How to add Root CA Certificates to ET1?

Hello everybody!


I've been working on a Sencha Touch app for an ET1 Tablet. In this app I need to access to a sever on a internal network to consume some webservices.


The app itself works fine, but despite I install the CA Certificates on the tablet, I can't access the server.


I've tried with other device and the access was successfull, but if I try with te ET1 there is no way to consume the webservices.


Somebody have any idea why that doesn't works?


Thankyou for your help!
