http://androidforums.com – Hi there, I have just bought a unlocked Dell Aero, when I insert my SIM card and turn it on I always get the following message "Sorry! The process com.android.phone has stopped unexpectedly. Please try again." with the buttom "Force close". After click it the first time, this alert poup up again for each 5-10 seconds. I'm not able to use my phone. I have searched on the internet for solutions, also inside this Forum, but anyone worked to me so far. Anything about contacts, SD, or factory reset. Anyone may have another tip/suggestion? I'll really appreciate th (General)
