I currently use a Motorola WX345 on the Consumer Cellular network, and just purchased a Motorola Bravo on eBay to replace it (the Bravo was used on the AT&T network). I swapped the SIM card from the WX345 to the Bravo, and now I get a MotoBlur setup screen. I cannot get past this setup sequence. Do I need to purchase an unlock code? Since Consumer Cellular uses the AT&T network, I thought I could swap the SIM cards and everything would work. I am a complete newbie, and would appreciate any assistance. Thanks in advance.
