Didn't see that.... did you now?
I was just here...using my stealth app...
actually it isn't really an "app" per se ...
More of a technique I lifted from an old sherlock holmes story ...involving writing invisible ink letters in lemon juice...so once dry they disappear..until the paper is heated...and then the words become visible again...

So step one...
grab your n900...a basting brush and a jar of lemon juice...

Step two...
Baste.

Step three...
allow to dry...

once dry ...
Step four ...you should be able to stealth surf with anonymity ...
(although you may find the slider and keys sticking a little..)

once done and you want to come out of stealth mode...
Step five...
Light a fire and hold your n900 over the flames with your bare hands ...
the screams you make will definitely be less than stealthy.....signifying you must indeed be out of stealth mode .

(jeez I am on a roll today...I should really monetize myself and get this stuff syndicated...)
