AT&T or the others?

With the passing of the IPhones 2 years of existance, many of the original IPhone owners had to justify continuing with the so called AT&T monster or move on to another carrier. The fact that AT&T had changed its policies on making the data plan MANDATORY (as of September of this year) and that the original IPhone owners could not unlock their cell phones (despite there right to do so on a device that is this old & purchased) made the unwanted decision to move on to greener and a different carrier. AT&T and Apple may wonder why the sales of the new IPhone did not even come close to what they did when they launched the original, well this maybe one of the many reasons why. I can't (in all honesty) bad mouth AT&T for their support of service or in any billing errors (like other carriers have done in the past) but its Achilles heel of a poor signal in both cell and data 3g network was its killer. It is really not much better with either Sprint or T-Mobile, they too have their flaws but Verizon (that poor carrier that I personally will not see many more years in business) is the clear winner in poor service dispite their attempts to change. So when push comes to shove, I miss my IPhones larger screen size and easy ability to use like most Apple products provide but I can not continue another 2 years of a contract under those terms so I must move on like so many other original Iphone owners have.
