these "iPhone" domains will all be pursued by Cisco/Apple and end up back in the hands of the rightful trademark owners. simple as that, it's against the law.
i know, because i have been forced to turn over every trademarked domain i was lucky enough to get registered.
you can ride them out until the copyright holder gets wind of it.
here's an excerpt from the attorney for the very last one i had registered:
"Please contact me, either by e-mail at: ***@****.com or by calling (504) 731-7296, so that we may proceed with your completing the NSI Registrant Name Change Agreement or the equivalent and transferring “****products.com” to ****. I look forward to hearing from you in the near future. As I mentioned previously, if you fail to contact me by January 19th, I will pursue ****’s trademark rights under both the UDRP and the Lanham Act. I thank you in advance for cooperating with my client in this matter."
