I am switching from ATT and currently have the Inspire 4G. I love my phone and HTC, but ATT has no service in my area and I am dropping and missing calls daily. 4G is coming to my area in a few months, so I do not know how important it it is to get a 4G phone now. Will there be kinks to work out? Will 4G improve reception or just upload/download speeds? I really like the Motorola Droid x2 but it is not 4G - but does have dual core. The charge is beautiful but I am not familiar with samsung phones. The thunderbolt would be my first choice since I love HTC, but this phone has had a lot of problems and I am a little worried about that. Any advice would be much appreciated!!!! I need to make the move asap.
