thunderbolt is better because is works better than droid
There is no Droid Thunderbolt. There is the HTC Thunderbolt. I would recommend the Droid Incredible 2 which came out in the past month. It dose not have 4G like the HTC Thunderbolt but It is far more powerful than the Droid Incredible and will be worth your while.
I would prefer to get the Incredible because (from my experience) the Thunderbolt is not as good as it looks.
The Droid Incredible is better than the Droid because it is faster, its lighter without the slide out qwerty keyboard. (The keyboard on the Droid sucks anyway.), and HTC sense in better than stock android.
yes
No
I would get a Motorola GSM 3200
Yes it runs android 2.2 Froyo.
Galaxy s4
droid x
droid x2 is better ... it is very easy to use..
It really depends on what you define as better. The iphone is said to be faster, and have more applications, but the droid is said to have better calling features.
It depends on what you want to do. The Droid X is slightly faster and has a better camera while the Droid 2 has the physical keyboard. In my opinion the Droid X is better.
