Verizon has really been playing games with OS releases by releasing OS 188.8.131.52 for the 8130 and 8330 over the weekend and then yanking them back down. Luckily the team at Cellular South have left the OS up on their download site.
You can just use their version if your hankering for an official version and delete the vendor.xml file. Or you could just wait for Verizon to re-release the already dated version of OS 4.5 again…
You can find the Cellular South version at this link:
Or you can keep an eye out for when Verizon will release it again at this link:
Thanks Tom, DavidB, & TC for sending this one in!
