ICS is cool, but... the official ROM is still laggy. So I decided to take further steps to mod it to CyanogenMod.
So if you are like me, want a smooth UX, follow the following optional steps :)

Root

3. CF-root by Chainfire.

Recent activity on my Gmail just revealed that there's this app "Authorized Application (225019099301.apps.googleusercontent.com)" from IP address 54.235.159.144 assessing my Gmail.

The IP address is from a Amazon server ec2-54-235-159-144.compute-1.amazonaws.com. (IP Lookup).

And blacklist check (http://whatismyipaddress.com/blacklist-check) shows that the IP is clean too.

Clicking on the "Manage Account Access" didn't give any information on the application "225019099301.apps.googleusercontent.com".


After Googling, it appears that the app is Mailbox (source: http://productforums.google.com/forum/#!topic/gmail/9LVW_etXyTE)

To make things easy, Google should show the applications with their ID.

Generate GoDaddy SSL Certificate (.crt) for Azure Websites (.pfx)

Step 1: Getting GoDaddy SSL cert.
Let's say you have a domain name of my_domain.com. You'll first need to generate the the .csr file for GoDaddy with the following command:

openssl req -new -newkey rsa:2048 -nodes -keyout my_domain.com.key -out my_domain.com.csr


This gives you 2 files:
my_domain.com.key - This is the private key
my_domain.com.csr - This is the Certificate Signing Request


Copy the content of my_domain.com.csr file to the SSL signing authority (GoDaddy).



Once approved, GoDaddy give you back a .zip file with the following 2 files:

18f1c77f369c0b59.crt - This is your cert
gd_bundle-g2-g1.crt - This is the GoDaddy Certificate Chain


Step 2: Convert a CERT/PEM certificate to a PFX certificate
openssl pkcs12 -export -out my_domain.com.pfx -inkey my_domain.com.key -in 18f1c77f369c0b59.crt


Step 3: Certificate to Upload to Azure.


Step 4: Assign SSL Bindings.




Step 5: Done!
