Jakob - I have been meaning to do a blog post with some detailed descriptions and instructions etc., but just never had time.
I did post a short demo video on here a few months back:

It's a fairly simple app, but the setup *looks* complicated (it's not though). Basically, you have to:
* Plug your Axe-FX into your PC or Mac via USB or MIDI cable
* Instigate MIDI over Wifi. On the Mac, it is simply a part of the Audio/MIDI settings in the control panel. On the PC, you need to download the free RtMIDI app. This will link your iPhone/iPod to the PC via WiFi and allow you to transfer Midi.
* Fire up AxePression and set up the MIDI messages you want to send using the finger gestures.
That's it - you can now use the iPhone or iPod to send MIDI controller messages to the Axe-FX (i.e. control the Wah pedal or Volume etc. as I do on the demo in the link above).
I've been asked a few times in the past few weeks, so I better make some time to do a detailed post about the setup.
