...this not well coded add-on screwed my kbd, I had to switch my kbd to spanish so I can get the sub-characters (the fancy letters u get when holding the keys), it was easier to hold the n and get the ñ to show up, after installing this thing I had to remove the english kbd and leave the spanish kbd as default....
for me iphone 4 its working on US keyboard & Uk Keyboard both, i read the comments later, when i installed it, it wasnt working then i rebooted my device and it start working after reading these comments i chked out my keyboard that was UK then i shifted to US as well it works on both, but these are not just till numeric five, 6 is also full of symbols but when we see 7-0 it gives us just blank thing but when we press it then thick black line appears and in 8 some art work kind of iphone is written, and i saw them on my 3gs but i tried on nokia no symbol comes on that just small blank boxes. these are not emoticons these are symbols, but some are really cool, but all of them are too sharp and neat. good work.
