Apple appears to have limited quantities of 16GB iPhones available, with the product not yet available in Germany, Austria or France.
The UK market appears less affected by the seeming shortage, with the 16GB iPhone listed as available now on the Apple online retail store here.
Not so in Germany, Austria or France, where the 16GB version isn't yet available, while US customers are facing a 5-7 day wait for the product to ship, a report claims.
Potential iPhone customers in Germany, Austria or France may not have to wait too long, as a T-Mobile spokesman believes the product will ship within four weeks.
It's not known if customer demand has exceeded estimates, or if the seeming shortage reflects the need to ramp-up manufacturing to product the new version in high quantity.
