I guess a few carriers were in cahoots on this one, and it looks like they all decided to release OS 188.8.131.521 for the Curve 8900 at the same time. Carriers Cosmote, Globul, Jersey Telecom, Mobiltel and Sunrise have all released an official version. You can hit up the links below to download from any one of them (just delete the vendor.xml file if the carrier is not your own) and get in on the action. Be sure to drop a comment and let us know your findings. Thanks Phillip!
