T-Break posted a review on the i-mate JAMin
Connectivity-wise, the JAMin is excellent offering Quad band operation along with GPRS, 802.11b Wireless Networking and Bluetooth 2.0. About the only thing left out is a 3G connection. We were easily able to connect to GPRS or a WiFi network as well as exchange files using Bluetooth and the PC or other phones around us. Keep in mind that using any WiFi has a big drain in battery.i-mate JAMin Review
