Thanks for all the replys. This is a tough desicion. After deciding on a os I then need to choose the phone. Having T-Mobile if I decided on a Windows Phone it would be between the Nokia Lumia 710 and HTC Radar 4G. Any opinions on these two phones? Sorry for asking so many questions but I want to make the right choice.
Depends on your priorities. Here are the areas in which each phone shines:
Lumia:
Clearblack screen is unsurpassed for direct sunlight viewing
Faster clocked processor @1.4ghz vs the Radar's 1ghz (the Radar is no slouch though)
Pedigree of legendary call quality
Nokia drive app
Radar:
Slightly larger screen could be easier for large hands to use (extra 10th of an inch)
FFC
WiFi sharing
Main camera has received more positive reviews
Best battery life of all WP7 phones
If you're wondering, I'd go with the Radar. Cost could be a consideration too. If you don't want to be stuck with it for 2 years, the Lumia has a lower off-contract price.
Oh, and I don't have a home internet connection. (broadband isn't available where I live) I have managed just fine driving into town to use MCD's free WiFi for updates for my HD7. Both are solid devices, though.
