Hello, Yesterday I installed 2.1 android os (because it showed up on my Ericsson PC companion that i needed to update s/w). Everything i did was absolutely legal/original as prompted by sony s/w. I followed everything, and the phone worked great for a while. Suddenly I noticed that I was in airplane mode, switching it off, didnt help, because it basically switches on immediately. I tried it a 100 times but still... I tried reading a lot of things online, but nothing helped. Restarting, reinstalling, I am completely clueless on what to do. Please can someone help me out !! I am w/o a phone now for a day now ! please ! Thanks a ton !
