Belgian iPhone customers will have to wait a bit longer than the earlier-announced July 11th launch date, since the device is subject to a law prohibiting a device to be sold in conjunction with a required subscription. French language site MacBidouille reports that the law counters Apple's plan of offering exclusive arrangements for some countries, since the lack of a contract would mean that the device would not be tied directly to Mobistar.
A revised date was not readily available from either Apple or Mobistar.
