According to CBR Online, Hutchison 3G has locked down the new Motorola A920smart phone for its "3" service. Symbian Ltd confirmed to ComputerWire last week that the A920 featured a "closed" version of its operating system, but 3 has only just confirmed what this means in practice. A spokesperson for the operator told ComputerWire that the device was being treated as a "walled garden" with users only able to install 3-approved applications on the device. By doing so, Hutchison is preventing users and developers from taking advantage of the basic similarities between the A920 and Sony Ericsson's established P800.
