I live in the northeast of Philadelphia and currently on Verizon's network using the iPhone 4S, it's terrrribly slow! I am receiving on a great day 825 kbps down 100 up. In my house... 200 down 40 up, sometimes less. Thinking about switching to AT&T. AT&T in my area can get up to 3 Mbps down 1.5 up. Problem is I have unlimited data with Verizon. AT&T is going to cap me. This is not an issue now with 3G speeds because I use wifi all the time. I am worried come LTE time for next year, I'll be stuck capped. So looking for some thoughts and opinions.. What would you do?
