I'm almost at my upgrade period. I was under my friends plan, but he wants me off, therefore I won't have Verizon anymore. Another friend said I could go under her plan, and she has US Cellular. I was looking at this device, and it looks great. How happy are you all with this phone? Is it worth upgrading to it? I was also looking at Straight Talk, but found out I couldn't use my Bionic with it. Can this phone be used with Straight Talk?
