Forum Adding Custom Profile field?
 

Is it possible to add a custom profile field to a specific style? I have two styles installed, one for mobile users and one for the desktop users. I want to add a field to the mobile style, for instance, if a user signs up, he/she will see this extra field asking them to enter their device's make/model(Nokia, HTC, etc) but if that user signs up from his/her computer, this extra field should not appear.

Thanks in advance
