Newly Launched MVNO cool.Prepaid has already appeared to run into trouble. Soft-launched in December and formally kicked off last week with a relationship with retailer Sears and a deal to distribute Motorola handsets with its pre-paid SIMs (in some cases, the hot RAZR and SLVR handsets), the MVNO is suddenly down to just selling the SIMs. Motorola has confirmed to several news outlets that it has ended its very short relationship with the company and is no longer supplying handsets. GigaOm and PhoneScoop are saying the company isn't even able to deliver on the SIMs at this point.

Meanwhile, cool.Prepaid's Moto handsets are changing hands on eBay. Hurry and get a collector's item! Watch this space.
