You could, of course, stop here but images like this always look better if theyre a bit more active, so lets give it something to display.Select the Screen Middle layer and then choose the Text Tool. For this image I set the text attributes to regular, 88px and crisp. The colour is black (obvious really).The envelope is from the standard Windows Wingding set and corresponds to the asterisk (shift 8), the text is Hattenschweiller but any font could be used.Once you have the text the way you want it, click the layer entry in the palette, this sets it down and will allow you to move, rotate and stretch the text using the Free transform tool we discussed earlier (CTRL+T for PCs).You may notice that even though it has been rotated, it still doesnt look quite right, this is because of the perspective of the phone. You cant distort text while its in this state, so the next thing you need to do is make it a Raster Layer. This is done by choosing Layer > Rasterize > Type. You can now distort it the same as normal image layer using the different transform options listed with the transform tool.Again, lining up can be tricky, especially as the text is quite small and there isnt much of an edge to go by, I used the same method as I did with the original heart shape of stretching it out to line it up and then sizing it back down again, once Id created the distortion.Set the opacity of the text layer to about 60%, this will take the boldness of the text away. You may also want to add a little shadow (which can be seen on some LCD displays) for added realism. To do this, select layer blending and use the default drop shadow settings.
