German newspaper Die Welt is reporting in their online version [GER] today that Apple is about to win tens of thousands of new corporate customers for their iPhone.

German mega bank Deutsche Bank and other corporations are apparently willing to add the 3G iPhone to their line-up of cell phones provided to employees. Until now, Blackberry models dominated this market segment in Germany. In the last few weeks, several high-ranking Deutsche Bank executives seem to have forced their employer to consider the iPhone as an alternative.

Since financial institutions have particularly high security standards, Die Welt reports efforts are currently being made at Deutsche Bank to meet internal demands in this area. Deutsche Bank is the world’s tenth biggest bank.

The newspaper goes on saying T-Mobile [GER] is currently negotiating with several other big German companies to win framework contracts. The German carrier for the 3G iPhone claims they already received “thousands of pre-orders” for the new Apple product from corporate customers.

The 3G iPhone goes on sale in Germany on July 11th.
