Mobile phone shops started selling iPhone 3G in Turkey. Turkcell and Vodafone received 200,000 applications for this phone. 8 gigabyte iPhone will be sold for 645 Euro, and 16 gigabyte for 758 Euro.
First-generation iPhones are sold in six countries but have been taken to many others and modified to work on local telecom networks.
"It is clear there is a demand for iPhones in many more countries," Apple founder Steve Jobs said while unveiling the new device last month.
It is designed for faster Internet downloads, longer talk times, and takes advantage of the high-speed third-generation (3G) networks to provide built-in GPS mapping.
Early iPhone 3G reviews have been favorable, saying the device delivers as promised but expressing mild disappointment with battery life. The higher performance of the 3G network saps power faster than its predecessor.
Apple will sell iPhone 3G models in the United States for 199 dollars and 299 dollars, depending on memory capacity. The original eight-gigabyte iPhone was priced at 600 dollars when it debuted in June last year.
IPhone 3G prices in some countries will be as low as a euro (1.57 dollars) provided customers purchase multi-year service plans that translate into lucrative long-term revenue streams for carriers.
Apple is continuing its strategy of locking iPhones exclusively to one telecom carrier per country.
IPhone service providers are AT&T in the United States, T-Mobile in Germany, O2 in Great Britain, and Orange in France, where iPhone 3G launches on July 17.
Belgium will evidently be home to the most expensive iPhone 3G devices, which will be priced at 826 dollars (525 euros) and 968 dollars (615 euros) because law there prevents subsidizing hardware costs with service plans.
Apple and numerous technology websites have posted online tips on how to navigate Friday's anticipated buying frenzy.
