MobibluAmerica.com certainly does appear to have gone MIA. I just returned a horrific Cube2 in exchange for a 1500i 2gb. First day I had the Cube2, charged it up, put ONE song on it to test and it started fine but then all of a sudden said "Bye" and never came back up. CRAP! My old 1500i 1gb went through over 700 chargings and 700 days at the gym being sweat on, dropped, banged around against machines & weights, worked like a champ constantly until the battery gave up the ghost and wouldn't hold a charge. It lasted almost 2 years to the day, I bought it originally in August 2005 from Walmart.com.
Either Mobiblu is done marketing directly into the US and will do it via sales partners or rebranding or they've so badly screwed themselves with customers here they're running & hiding.
