AT&T WIRELESS - CINGULAR WIRELESS Internet Charge is Outrageous Internet

I have been with AT&T for about 6 months now and I am already on my 5th blackberry 8900 smart phone. AT&T advertises that they have the best 3G network for internet services; this is totally untrue. I pay the minimum $30 a month (min for smart phones) for service that I do not get. I have spoke with technical support numerous times and they say the reason is that it depends on where I am located. I understand the designated towers that help to gain internet connections, but how can a company advertise that they have the best network? Technical support has also investigated my phone and says that the phone is working probably.

Every time I try to use my internet, it takes forever to load and I can not log into websites. My phone will display 3G, GSM, and Edge depending on my location. My smart phones speed does not increase with any of these networks. My WiFi is also on at all times and the WiFi does not increase the speed. The only comparison of the network AT&T offers is a slow dial up version of the internet. I am not an internet expert, but I know that I am getting ripped off. I am stuck with this blackberry smart phone until my next my next upgrade. I would cancel my internet to save money, but I need the internet so I can receive emails that are directed to the email application in the phone. The email application works like an SMS and has no comparison to an actual inbox. I wish there was some other alternative.
