I was originally thinking of leaving AT&T for Verizon to get the upcoming Droid X but not so sure I want to lose the grandfathered unlimited data plan I have and I also got to admit I like the voice/data simultaneous ability of AT&T's 3G network. With that being said, how bad am I going to miss push email, led/custom notifications? How easy is it to root aria and load whatever I want onto it? How do I transfer contacts? Can I still use my sd card with the photos and videos it currently has on them. Anyone made a similar transition?
