First off, you are not the only one. I am also a US Cellular customer with a Touch Pro. (But since I am new here too, guess that won't help)
Been with USC for about 5 years. Haven't found a better one that gives me the same or better deal. AT&T & Sprint, "0" bars in my home. (My kids have those and when they come to visit, they have to go outside to call or talk) Verizon is great, but USC had a cheaper plan. I don't know about the rest. I also wanted to install the 6.5 ROM but it can be a bit confusing since USC isn't mentioned in any of the unlock or flash post. And if you do a search for US Cellular it will come up invalid search (US) need at least 3 letters. And if you do one for uscellular you get 4 post. (Well now 5 since I wrote it in here)
