You can only delete tones from the User Tones folder. Tones can not be deleted from the factory, style, band, or customtone.com folders.

I tried again to follow the steps you provided, but am not experiencing what you have reported. These are the steps that I tried:

-Launch Mobile POD.

-Tap the presets area in the top center, select "Hairspray" from the 'All Tones' folder.

-Tap done in the lower right hand corner.

-Turn up the master volume on the amp.

-Tap save in the upper right, select 'save as'.

-Title it 'Hairspray1', tap save.

-Tap the presets area in the top center again to go to the preset view.

-Tap 'User Tones' and than load a different user tone,(you can not delete the current active tone).

-Tap edit in the bottom of the app, this will give you a red minus sign to the left of the preset name, tap it, you then will be given a red 'delete' button, tap delete to delete 'Hairspray1'

-Tap home button to exti the app.

-Double tap your home button, than tap and hold on the mobile pod app that should be displayed at the lower left hand corner of your screen, you will be given a red minus sign on the app, tap it to close tha app.

-Reopen Mobile POD, tap presets, look in 'User Tones' and 'Hairspray1' is gone.

Try it using the steps I provided to you above and see if it lets you delete the tone.
