The latest generation iPhone will make its debut in Ireland today.
The iPhone 4 boasts video chat, high-definition video and sharper screen resolution.
It went on sale last month in the North and the UK, France, Germany, Japan and the US.
Today it is hitting the shelves here and in 23 other countries.
The latest iPhone has been beset by various problems including reception difficulties and signal loss.
The white model has also been delayed because of "unspecified manufacuturing difficulties".
Apple has however sold more than 50 million iPhones since 2007.
