The Global Certification Forum (GCF) just approved the Motorola EX300 and as always, the GCF isn't spilling any beans what kind of device the EX300 is. However, it's most likely that it could be another Android smartphone from Motorola. It's supporting triband GSM/GPRS/EDGE at 900/1800/1900 MHz as well as dualband UMTS at 900/2100 MHz. While neither HSDPA nor HSUPA are supported, it's said that the EX300 is featuring UMTS video telephony. Therefore it can't be a 2G/3G module neither it's likely that it's just an entry-market mobile phone because Motorola's latest mobile phones were all called WX-something and non of them supported 3G.
In any case, with triband 2G and dualband 3G support, the EX300 can be a low-end (Android) smartphone only.
