Oh, linked lists... Have fun! Remember: each node knows only about the nodes in immediate contact with it (to its left and right, so to speak), if memory serves from that horrible Data Structures class! Anyway, the userAgent is mobile, as evidenced by the Apex's loading of Google, GMail, and Facebook mobile pages, among others, automatically.
