Honestly, the EVO meets my needs, not sure what I'd use a dual core phone for...
If I had one wish, it would be for decent battery life...
I think Android OS needs to improve more than the phones. Gingerbread is a disapointment.
A new HTC 4G Sprint phone is supposedly coming out next month with a slide-out keyboard that I'm eyeing. I really want a new phone as I'm done with my current phone cus it's really buggy and slow. It gets data lock-ups randomly and GPS takes forever to lock and battery life is worse than even the Epic/Evo.
