So the Walmart thing is still going on.  Bloomberg today confirmed (it's hard to keep Walmart's employee's mouths shut it appears) that they will indeed be pushing the iPhone.  Interestingly and contrary to other reports, they do say there might be a $99 model:

Analysts say Apple may offer a discontinued 4-gigabyte version through Bentonville, Arkansas-based Wal-Mart and sell it for $99. Apple currently sells two models at $199 and $299.

They go on to quote Shaw Wu:

“A $99, Apple-branded cell phone is inevitable,” said Shaw Wu, an analyst for Kaufman Brothers in San Francisco. “One of the key things Apple needs to do to drive broader iPhone adoption is to build a more complete product line” with low- end, mid-range and high-end products, Wu said in a Dec. 5 note.

Which means there is absolutely no chance there will be a $99 iPhone.  Ever.
