Sure we have seen Kevin’s Pearl 8220 unboxing before but The Boy Genius managed to take it on step closer. He has unboxed a T-Mobile branded Pearl Flip 8220. He also goes on to say that he isn’t teribally impressed with the overall quality of the product “As far as the device goes, we’re pretty disappointed. Not so much because it’s absolutely terrible, just because the Pearl Flip feels like a prototype and not a final build. Even though this is a retail unit.”.
