According to engadget

Verizon launching LTE network in December 2010 (video) -- Engadget

VZW will have 4g lte next month. I currently have the htc evo and live in a area with ok 4g coverage (scale of 1 to 10 i give it a 6). I'm wondering if anyone can answer these questions about vzw lte.

1. Will it allow me to talk to surf the web at the same time like sprint wimax 4g?

2. Anyone know if its gonna be a battery killer like wimax?

3. Say for instance I'm doing a video call in a 4g/lte area and while im driving i move to a non 4g area. Will my call be disconnected when I my phone switches to 3g? Or am i way out of the realm of possibility on this one?

4. Anyone know how much extra they are gonna charge for lte?

5. People all over the internet are saying that tmobile hspa+ is still faster. is this true?

6. Will it slow my phone down and make it lag like crazy like my evo when 4g is on?

Please... nobody tell me to google this stuff because I already did and all i could find was peoples opinions. I'm looking for cold hard facts... Opinions are ok too but... well you know!
