i-mate JAM
MobileTechReview has a review of the i-mate JAM, and concludes: “However, if you prefer to have a quad band GSM world phone that’s unlocked for use with any carrier, the JAMin is an excellent choice. If you’re an international traveler, you’ll make up the added cost in no time by avoiding US carriers’ overseas roaming prices.” The i-mate JAM’s battery life? “the JAMin with its standard 1200 mAh hour Lithium Ion rechargeable battery does quite well, lasting just under two days with moderate use (30 minutes phone time total using a Bluetooth headset, surfing the web over EDGE for 1 hour total, using WiFi and the web for 30 minutes more, and checking email and PIM data several times per day with Bluetooth always on).”
