I got two hits today, from different IP's (residential US broad band) where the referrer for both was instagram . com and the user agent contained a lot of info about the device (both cell phones).
Does anyone else ever see stuff like this? I'm curious how it happens, I don't own a cell phone myself, and a guy I work with doesn't have instagram on his phone so we couldn't simulate this today, he might try to get his kids to do it.
I'm thinking that someone sent a link to someone else using instagram? Can you browse a website using instragram phone app as the browser?
