Have you tried to push it manually by going to system settings, about phone, system updates? If that doesn't work goto droid razr hacks in this forum and look up the thread for the droid razr utility for jelly bean. You can download that to your p.c. and install it manually.
Is downloading the jb to a computer and the to the phone the only option? I have been waiting patiently due to the fact it was supposed to be released by the end of the 1st Qtr? I have tried to manual update to get the infamous "up to date". Shouldn't motorola or verizon supply a thread to upgrade OS systems?
