Summary Android 2.3 HTTPS/SSL checklist:

• If your CA is in Android's 2.3 list of trusted CA's -- and Thawte is -- there's no need to include the certificate in the app.
• Android 2.3 does not support Server Name Indication so if your server is relying on it for SSL handshaking, Android may not be getting the certificates you're expecting.
• Do you have certificate chain on the server installed, and is it ordered correctly? Most browsers handle out-of-order certificate chains but Android 2.3 does not. bdc's answer in the thread I mentioned above describes how to check the validity of your SSL certificate and chain with "openssl s_client -connect yourserver.com:443".
• When digging up that old 2.3 device you have in your bottom drawer, please ensure its date and time are set correctly after being powerless for too long.
