Set Down the Stone Axe and Do It Over the Air.

"Of course the current generation of devices presents challenges to those trying to architect OTA update systems. Android, in particular, tests the scalability of OTA servers with very large (100mb+) package sizes. These large packages have been a challenge not only for the operators who will have to send them over the network but also for OEMs. As an example, it seems that Sprint, with the THC Hero and the Samsung Moment, is at least giving subscribers a taste of Éclair but that flavor will have to be savored over the wire and not over the air because the packages are at 80Mb and 117Mb too large for Sprint’s current OTA server to handle (evidently the stuff they have in place goes up to 9Mb, too small by factor of 10-20x)."
