Pocket PC and Sony U owners who are looking for a CF based GSM solution for internet connectivity should take note of the Enfora GSM0110 CF card. The Enfora is a quad band card (850/900/1800/1900MHz) that ships with both Pocket PC and Windows 2000/XP drivers. There is an optional battery pack available to allow extended operation without draining the handheld’s battery. MobileTechReview has a complete review of the Enfora with photos of the device and the software that ships with the CF card. The card comes with a PCMCIA sleeve for use with any notebook computer but the card should work directly in the CF slot of the Sony U.
