My Alltel service has sold me to ATT. They sent me the HTC Aria to replace my BB. My IT guys at work all recommended that I switch to the Android platform. I was told that the switch from CDMA to GSM would probably not be complete until April. I'd like to start using my phone now, in some capacity. If I could load it with a few apps and use it for WiFi that would be great. So far, I cannot register on Android Market becaue I have no "phone" and although I was able to connect with my Wifi I cannot open the web. If I pull the SIM card, can I use it for some of these other things? It would be nice to be able to get to know my new device, since I have a couple of months before it goes live on phone network. If you can offer any suggestions, I would appreciate it!
