At Photokina this week, Eye-Fi, makers of the first Wi-Fi-enabled SD cards, announced two improvements to its product family effective October 5th:

• First, a firmware update will double the photo transfer speed from Eye-Fi cards from the current 350KBps to 700KBps.
• Second, users of Eye-Fi cards will be able to add the photo transfer features of their choice to cards that were not bundled with these features.

Here are the new options:

• Users of the entry-level Eye-Fi Home card can add web sharing for $9.99/year, making the card equivalent in features to the Eye-Fi Share card.
• Users of the Eye-Fi Home or Share card can add geotagging for $14.99/year.
• And, users of the Eye-Fi Share card can add automatic uploading at open hotspots or at Wayport hotspots (there are over 10,000 of those) for $14.99/year.

By adding geotagging and hotspot support, users of Eye-Fi Share cards make these cards equivalent to Eye-Fi Explore cards.

The already long list of online photo sharing services Eye-Fi supports now includes Apple's MobileMe and AdoramaPix, effective immediately. Eye-Fi cards are now being bundled with digital cameras at Wal-Mart.com, and will be available at Best Buy stores starting October 5.
