iOS 7 (WWDC 2013 logo mockup)

With a little over a month until Apple’s summer conference for developers, web site owners are now beginning to see a noticeable spike in traffic from devices that run iOS 7 beta code. Analysis of traffic logs and IP addresses reveals some of that traffic originating from Apple’s Cupertino campus, which is usually a tell-tale sign that Apple is seeding the work-in-progress code internally to select engineers.

However, the mobile site conversion firm Onswipe over the past week or so started seeing iOS 7 traffic spikes across a bunch of web sites that incorporate its solutions…

According to TechCrunch, Onswipe observed a “significant bump” in the number of visits from iOS 7 iPhones and iPads, specifically located in both Cupertino and San Francisco.

San Francisco had the most iOS 7 visits, with 18.75 percent, and Cupertino accounted for 17.9 percent of the total. May 2 saw the highest iOS 7 traffic to date, representing 23 percent, or nearly a quarter, of all unique iOS visitors to Onswipe-enabled sites. Most were visiting from iPhones (75 percent), but iPads also represented a full quarter of visits.

Wondering what those iOS 7 beta testers are doing on their devices?

According to Onswipe, typical activities include finding out about which turntable to buy, Vine’s recent front camera-related update, Apple’s stock price and Kid Cudi.

9to5Mac confirmed with its own sources that Apple’s design guru Jony Ive, whose responsibilities include Human Interface across the company following iOS boss Scott Forstall’s ouster last August, is indeed leading a major revamp of the mobile operating system.

There’s been no shortage of iOS 7 mockups over the past few months, here are three nice concepts.

The redesign apparently gets rid of stitched leather and other signs of skeumorphism in favor of a flattened and minimalistic appearance akin to Microsoft’s Windows Phone.

9to5Mac also separately reported that iOS 7 will include improved in-car Maps and Siri integration. Despite iOS 7 delay speculation, AllThingsD reaffirmed that Apple’s team is in “deadline crunch mode.”

Apple has reportedly borrowed engineers from the OS X 10.9 team in order to finish iOS 7 in time for an assumed Fall refresh of its iOS hardware.

Apple’s WWDC 2013 press release quotes marketing honcho Phil Schiller who confirmed that Apple will be getting “new versions of iOS and OS X” into the hands of its registered developers at WWDC.

The conference is scheduled to take place at Moscone West in San Francisco from Monday, June 10 until Friday, June 14. You can count on iDB to bring you both major announcements and newsworthy nuances, as they happen.
