I have put a Hydraskin (Malaysian site similar to Gelaskin except the whole metal band is skinned) on my iPhone. On top of this, I have applied a screen protector. There is a huge air bubble that is vignette-shaped due to the slight added bulk of the skin. Any ideas on how to remove this? It won't budge even when smoothing it with a credit card. Do I blast it with a hairdryer to make it conform to the shape? Alternatively, are there any affordable skins that are not stiff?
