The Droid 4 has a Qualcomm MDM6600 chip which technically can support both CDMA/EVDO and GSM/UMTS networks. You'd have to flash a different baseband though, which I know nothing about.
Ah, hope again, yet it always hangs by a thread.
The finest mobile I ever had for it's time was the nokia 5100.
It's form, shape and weight were idealy built, disregarding the design on an esthetic level.
Full of features yet able to take a beating, if it had GPS back then I might be still using it today.
Survived my sister's welding classes for a year after me, even after some keys were molded toghether.
Never after that did I have a similar experience with any mobile.
None have all the basic necessities such as a decent and efficient input method (qwerty/azerty keyboard), an affection albeit slight towards trying to have autonomy (native power saving function as the droid4 promises), being able to use the phone freely without having to live around it and being careful in the rain (Motorola builds them well, this one can take a drop of both water and gravity, scratchproof glass helps as well), etc.....
I simply refuse to buy a phone of which the general public thinks it's the best, and having to also purchase satin gloves and tweezers to be able to use it.
All ranting aside, I'll look into flashing etc and if it's reasonably doable, thanks for the tip!
