iPads with 2048x1536 displays and/or unreleased versions of iOS are appearing in server logs, Ars Technica remarks. In February the website saw 346 visits from a device with a 2048x1536 screen, which is believed to be the iPad 3 based on numerous reports and the rarity of such a resolution. Tracking iPads in use from Apple's corporate IP block in Cupertino, meanwhile, Ars says it has encountered devices running not only iOS 5.0, 5.0.1, or the developer-only 5.1, but even an unannounced iOS 6.
