Up and down we go

Another up day today after Wednesday's ugly sell-off.

The new Apple (AAPL) iPhone with faster 3G wireless technology goes on sale Friday morning. As with the first iPhone, there's been a lot of hype and varied reviews on its performance and worth.

But Farnoosh Torabi of TheStreet.com took an interesting look Thursday at what the real cost of the iPhone is to a person's potential retirement fund. It's humorous and insightful.

I kind of want an iPhone, but I think I can wait.
