hanging your icons with XS++ is actually very easy, it only takes time to break through the CID49 security.
What you need is the latest version of XS++

You extract it somewhere, preferrably somewhere where you'll find it
Then we need an icon pack to upload to the phone, there aren't much of them at the moment, but there will be more.

I've added some of them as attachements.

you copy the (unzipped) icon folder, should be all as in the structure inside the phone, beginning with the map tpa.
Inside the folder where you unzipped XS++ there should be a folder called files_to_upload.

Just copy the tpa folder with the icons it it to files_to_upload.

Now that the icons are in the right place we can open XS++

When XS++ is started you can connect your phone like you connect it for an update with SEUS. So you shut down your phone,
take out the battery, press the 'c-button', reinsert the battery and still holding c, connect the usb cable.

When it's the first time you connect it like that your pc will show a message 'new hardware found, insert media etc...'
just click on install software automatically, it should find something.

When you install it it'll give you a warning that the software isn't conform to
the windows XP logo test.. just ignore it and continue anyway

Ok now you click in your XS++ window on start and connect it again the same way.
It should look like this:
Then click on FSX and then on Start FSX


You are flashing you menu icon at your own risk. 99.9% safety first.
