The PDF mentions a few things that are note worthy though. The file could take anywhere from 20 to 70 minutes to download, based on your data connection at the time, we always recommend Wi-Fi of course. Also, the file size is is roughly 354MB’s and during the install your phone will be rendered useless. So don’t plan to make the update on your lunch break if you need your phone for work. Of course the good news is that it will be coming through via an OTA in the very near future. If any of ou see it pop up, we would greatly appreciate an email, G+ or twitter alert that it is rolling out. Until then, check out the PDF file dropped by Verizon that explains everything. Also, you may want to visit Motorola’s site for ICS videos and information about your update ahead of time.
