Cheapest Nokia E71 Unlocked Phone with 3.2 MP Camera, 3G, Media Player, GPS, Wi-Fi, and MicroSD Slot--U.S. Version with Warranty (Gray)

Some notes to consider for this phone:

3G -- Despite Amazon saying this is the US Version of the phone (which it is,) this phone does NOT work with T-mobile 3G in the US. T-Mobile 3G in the US uses the 1700 mhz spectrum (you can read on wikipedia as for the reasons why) and there are no 3G roaming agreements with AT&Ts 3G spectrum like there is with EDGE. That being said, I have found that EDGE is fast enough for my web browsing and e-mail use (220 kbps+.) Using GSM/EDGE only also more than doubles your battery life, so this is not an entirely bad thing for T-Mobile users. The 10 hours talk-time and 17 day standby is no joke with GSM either.

Network Settings -- Nokia has a great website that will text you all the internet, voicemail, and MMS settings for your carrier to the unlocked phone.

Bluetooth Tethering -- This phone does not tether with Mac OS 10.4 Tiger. It does tether perfectly with 10.5 Leopard. It tethers with Windows XP via included Nokia PC Suite. It would be nice if a Mac suite were included from Nokia but Apple provides everything necessary with Leopard. It obviously tethers perfectly with Nokia N800/N810.

GPS -- The GPS in the phone is first class with both an actual GPS receiver and assisted GPS through cell tower. It works much better than my TomTom One especially indoors. The phone comes with a great program called Maps but the only drawback (and it is a HUGE drawback) is that you have to pay a monthly fee to use any sort of route guidance. You're allowed to see your position and browse maps for free but if you want to plan a route it costs extra. It comes with a 7 day trial that you should save for emergencies in my opinion.

Networks in General -- This phone works great on both AT&T and T-Mobile but each has their drawbacks. AT&T has the faster network but limits you to 5Gb/month bandwidth and charges extra to tether. T-Mobile allows actual unlimited data on EDGE and allows free tethering to any device but has the slower "2.75G" EDGE data network. Wifi is available on the phone and works flawlessly.

Third Party Apps -- Two must have apps are the S60 Divx player and the Slick IM client (AIM, Jabber, Etc.) The Nokia mail client works great and a third party solution is not necessary.

All in all this is a first class phone whose only missing feature is a touch screen. Depending on your need for a QWERTY keyboard I would say this and the N95 are battling it out for best phone in the world right now.Get more detail about Nokia E71 Unlocked Phone with 3.2 MP Camera, 3G, Media Player, GPS, Wi-Fi, and MicroSD Slot--U.S. Version with Warranty (Gray).
