Just last week we saw OS 188.8.131.523 leak for the Bold 9900. Now, A1 is making that build an official release. If you have already installed the leaked version, there shouldn’t be a reason to install the official build, as they’re the same. Let us know if you find anything new. Be sure to delete the vendor.xml files should you decide to load this OS on a non-A1 Bold 9900.
