It's so ironic that majority of these posts are just saying that they will try the trick but none of them are feedback.
Regarding with the trick, it's not working.
The trick is tested with MyPhone TW1 Duo, and it's working. It might also work with other Java phones.
Unfortunately, it only restricts to Facebook only, so browsing to other sites will redirect to connection error, even if I tried with the FB code.
At least FB is working for OM.
Let's hope...
