Vodafone yesterday announced to offer a data-plan for customers who actually bought an unlocked iPhone in a foreign country. The data-plan requires a normal fon-plan by vodafone, means: the iPhone plan is an upgrade. The interesting point is the price.

This flatrate costs 9,95€/month surcharge to a current fon-plan. It gets slowed down from HDSPA to EDGE/GPRS speeds after having transmitted 500MBytes.

In contrast to original T-Mobile Germany iPhone plans Vodafone does not permit using Voice-Over-IP (VoIP), Instant Messaging (IM) or VPN – means they tolerate that you even jailbreak your iPhone in order to install third party apps, that are not provided through the official Apple AppStore.

The struggle for the cheapest iPhone plan has begun.
