Deutsche Telekom's mobile unit T-Mobile is now offering Apple's iPhone in Germany without a service plan, after Vodafone raised questions about the exclusive agreement which binds the two companies.

The Regional Court of Hamburg ruled that Deutsche Telekom could not offer the iPhone solely with a two-year service plan and with a SIM lock, which prevents the device from being used on other mobile networks

Vodafone had won an interim court injunction on Monday.

The iPhone is now available free of any contract and SIM lock for €999 ($1,480) from Deutsche Telekom retail outlets. With a service plan, the iPhone costs €399 ($591), in combination with a 24-month contract.

In a statement, T-Mobile said it would comply with the court order until the issued was resolved.
