My ASP.NET website hosts calendars in ical format. These are accessed via a simple service. I log the user agent string (context.Request.UserAgent) to a database.
The vast majority of my calendar requests are from a user agent that identifies as “DataAccess/1.0 (XXXX)” where xxxx is a variable code (eg 8J2, 8C148).
I’ve searched on http://www.user-agents.org, http://www.useragentstring.com and Google
What is this user agent?
They are older iPhone clients of some sort (the XXXX corresponds to the OS release, 8C148 is 4.2.1, 8J2 would be later, probably 4.3.something).
