Is there a way to download OTA update in Italy?

[dasaucemasta]

I am currently studying abroad in Italy until December but I still use my thunderbolt for everything - its my camera, my mp3 player, and I can use wifi to make calls on Skype and use the web. I was wondering, since I obviously cant connect to the Verizon network, if there was any way I could download the OTA from somewhere else online onto my phone? Or does it have to go through the official OTA through Verizon's network? I am not rooted and dont want my phones memory to be wiped either
