unfortunately no matter what i choose the "capacity" issue remains. 3g or 4g. basically described it as a traffic jam on our local towers....
If you absolutely must have a reliable data connection today the the answer is to go wit a 3G device. I have experience with a Droid X and it is a superb device.
The correction to this problem will be coming ... it isn't here yet ... my guess it 2-3 months should be your expectation for a business decision.
There are spots only a few miles from me that have lousy reception from Verizon and great reception from US Cellular. Save the call to Verison ... the only way you are going to know is to move to your new location and test it in the environment(s) where you operate most.
I think the Bionic is a great device and I am heavily on WiFi so the data drops do not affect me as much as others. I have customers who work out of trucks and rely on data for their day-to-day work. I tell them to stay on 3G for a while.
Must have data today - go with 3G
Can live with data drops today - take the $120
