Verizon Alltel Merger..Better signal?

[flyinace123]

I've had a TP with Alltel (now verizon) for about 10 months. From day one my signal stank in my house and at my office. Is it possible to lock onto the Verzion towers now that the Verzion/Alltel merger is complete? A couple guys I work with have had Verizon for years and they always had full signal in the office while I had little to nothing (often no signal at all). I was hoping I would now have a full signal but nothing has changed. Do I have to do anything to get the Verizon signal on my Alltel TP? Should I bring it into a Verizon store and get them to do something?
Also, can I now get 3G internet speeds on my TP now that the meger is complete?
