I recenty updated my GT540 form the offical 2.1 to 2.3.7 C7.I had no problems at first, but after a week i noticed that my phone gets "sd card removed unexpectedly" message.It happend rarely like one per 2 days, so i kept fixing it by pulling the card out and pluging it in again.But a week before i got the message again but after repluging the card nothing happend.I tried hard reset, other cards, reinstall the ROM, other roms, but nothing helped at all.Now even with a card in my phone i cant use Galery, Music, or anything else that requires SD.Its like no card insterted.Any ideas how to fix this?
