Motorola V600 Phone (T-Mobile)
Love this phone!!!!!!
This phone is among the best I've owned.  The color screen is fantastic, but I truly like the technology features this phone has built in; things like BlueTooth support which I use all the time to sync my calendar with my PC and for my wireless headset.  The camera works great, though I think there are higher resolution camera phones out there now if that's important to you.  Call quality has been top-notch, and the battery life is among the best I've experienced with any phone.  The software is sometimes slow to respond (imagine a PC that needs a little more RAM to speed things up, and you'll know what I mean), but its not enough of an issue for me to affect my overall rating of the phone.  Size/form factor is also perfect for me.  If you're new to Motorola phones, I've never liked the way they organize their phone book entries, but this is something you simply have to live with when you buy a Motorola phone.  I admit I haven't had the opportunity to use this phone in another country's GSM network, but its nice to know the phone has the flexibilty should I need to jet off to Europe for work!  All in all, its a phone I highly recommend.
