After probing the firewall logs, it appears that the grey/blue icon is triggered depending on whether or not your device has access to Google Play. In our case, I had to open tcp-udp port 5228 (as per http://support.google.com/googleplay/bin/answer.py?hl=en&answer=2651367) and after turning wifi off and back on again, the icon became blue.
I can't ...

This isn't built-in functionality, but it's something you could achieve with a trigger/event app such as Tasker. This kind of app runs in the background, and lets you configure certain actions to take (such as turning off the ringer) when certain events occur (such as seeing a particular Wi-Fi network). Tasker's not the only such app, but it's very complete ...

As best as I can tell on GrepCode, functionality relating to walled gardens (captive portals) was added to WifiWatchdogStateMachine.java in 4.0.1.

What do you mean by having a "a bar" on the SIM card? I don't fully understand your situation but I'll try to give you an answer you can work with. I've checked out Giffgaff and apparently this is a pre-paid network in the UK.
Let's forget about Internet for a second. Can you make calls with the Giffgaff SIM card in the phone? If you can, then you know your ...

Tasker is an app that can be used to automate changing settings on your device, based on various events like when you leave range of a wifi AP, or when you enter a geographic area.

On newer versions of Android, WiFi settings are backed up along with your Google account (If you've enabled it in Settings -> Backup & reset -> Back up my data), and restored when you link your Google account back to your wiped or new device.
Note that in my personal experience, the Google backup feature is a bit flaky, sometimes it works, ...

It is possible that your phone connected to it because it is an open network, which means that no password is required to connect. You can disable this feature by going to:

Setup-Method: Netd-Ndc (master)

#!/system/bin/sh
sqlite3 /data/data/com.android.providers.settings/databases/settings.db "UPDATE secure
SET name='mobile_data',value='0'
WHERE name='mobile_data'"
You can add this as init.d script, if your ROM supports init.d. Or else you can patch boot.img with autobootimage patcher from xda.
The above script is for mobile data: for Wi-Fi, change ...
