I haven't heard NY-Metro 4g has issues. I have experienced and read similar experiences regarding the T-Bolt in the NY-Metro area. What I've been noticing, and I could be wrong, is that most people that purchased their phone within a 4g hot zone from a vzw corp store and did the auto-registration for the sim card on the spot have been having little or no issues accessing 4g. This precludes the extended 4g coverage areas where the known issues regarding network transition occurs... this I think we all have and the update reportedly fixes.
Question I have is how does a tech in a non 4g zone verify data flow over a new sim activation?. I understand they can see the actual sim auto-registration online but how do they test actual data transmission?. It's not like they can just open up speedtest.net and verify that 4g works. This also goes for those people that get their phone in the mail who maybe don't live in a 4g zone.... but maybe work in one.
I purchased my phone from a store with no 4g coverage and noticed that the operator activating my phone was having difficulties. Once I left the store and started to realize I had no 4g data, even though the radio gave my full indication at times. I attempted all the reported fixes still with no success. I decided to take it to a corp store I knew had strong 4g coverage to review the issue. Long story short... they fixed the problem by replacing my sim card. I verified the fix inside the store and discussed with the operator who replaced the card what seemed to be the problem. He ran me around the usual circles but what I did get was that the card had been registered twice in their system by an operator more than likely inadvertently which we know now will render it ineffective.
Not saying this is the reason that some people are having issues.... just an observation.
