Here’s why I ordered myself a BlackBerry 8707v from eBay (3G, quad GSM) and am ditching the E61.
On my last trip to the far East (China, HK, Taiwan, Singapore) I bought the Nokia E61 phone + PDA. This phone is quad band GSM (for best North America coverage, yes, places in the US still use 850 MHz) with 3G (2100 MHz, Europe only capability), bluetooth, Wi-Fi (802.11g/b). This is a true world phone, expanding its coverage into the previous no-man’s land of Korea and Japan (3G). It also has Blackberry capability via GPRS/EDGE. I paid around $410 USD after tax rebate. It can be purchased on the internet for $350 + S&H.
