just installed the update, and after a few switches from 3g for internet, and then back to 2g iam unable to get any cellular network signal !!, i've tried uninstall, reboots, taking sim card out. but no luck!, charging up my old phone, just to make sure its not the network that is down
- i have been using the older version i had no problems

lol panic over!!, all seems fine, after taking out the sim card and cleaning it i've got a signal again.
