been having problems with my phone... just read the tips on memory card problem and realized that my MicroSD is class 2 !!! and that 5800 has a known compatibility problem with class 2 cards.

Since mine is an original set.... will nokia care replace it? Its is proven that class 2 cards are not usable with it?

Since i bought the phone i think just a year back, been having on and off hanging problems if i open apps too much.... even sent back to Nokia before when the phone refused to get out of startup screen. They checked it and jstu said it was software problem.... no one mentioned about the card.
