New evidence of Nokia's upcoming Windows Phone 8 devices surfaced yesterday following the discovery of a bright yellow Lumia "Phi" prototype last week, and now yet another pre-production bezel has appeared. A rectangular bezel similar to the one used in the Phi was uncovered in a forum thread on WPXAP, but there are a few notable differences between the two. Among other small changes, the capacitive button area on the lower portion of the digitizer has been elongated, which could be due to a reduction in display size from 4.3 inches to 4.0. Nokia is rumored to be releasing two phones on the 5th of next month, so we won't be terribly surprised if variants of these parts make an official debut sooner rather than later.
