I have done this using a bootloader designed to be launched remotely
by special serial port data to the application, plus a watchdog.
Wireless that I've used  is (1) WiFi and Lantronix WiPort module; (2)
WiFi and Moxa NPort end-item; (3) MaxStream/Digi XBee - a pair, one at
the AVR and one connected to an on-site PC/server. All of these rely
on infrastructure on the premesis. 

Using public infrastructure like cellular data is a problem and
hopefully you don't need that.

I contributed BLIPS via avrfreaks.net in the Projects section. It can
bootload via IP on wireless or ethernet as well as Serial lines.
