I have a 4gb microsd card in my
n95 for over a week and it didn't blow. Somewere in this forum it is said that the
n95 will be able to use up to 32gb cards.
I would not worry about that. Several owners are using the 4gb card without problems. I went from a 1 gb to a 2gb and then a 4gb, without any problems.
It is, even, working faster.
