iPhones (at the time of 2G) used to have a major issue, they would not fallback to the secondary DNS if the first failed.

Hi all,

Apologies for the spam, but can someone at AT&T Wireless with DNS clue
contact me off-list? Our iPhones are receiving intermittent SERVFAILs
when querying your DNS servers over 3G. We're trying to go through the
support chain but it's getting us nowhere fast.
