If you live in Europe or Canada, you might find that some apps are now a little more expensive on your iPhone or iPad. Yesterday, Apple informed developers that it would be raising prices before the weekend to reflect changes in VAT and foreign exchange rates. Those increases are now starting to take effect, with a 10 pence rise for the cheapest premium apps in the UK, up from 0.69 to 0.79, and a new 0.99 starting price in EU countries. The minimum spend in Canada (beyond free apps, anyway) hasrisen from $0.99 to $1.19, and Norway, which uses its Norwegian krone, should see a similar rise in price. Apple is tinkering with app fees in Iceland and Russia too, so if you live in any of these countries it's probably worth opening up the App Store to assess the damage.
