Replying to: BB 8310 Micro sd card space by M_Demon_Hunter
I have a very new 8110 with OS 4.5 on it, and can take up to an 8 gig card, and actually am using one. I have a friend that has a branded Pearl, updated to OS 4.5, but it can only do a 4 gig because the carrier doesn't sell anything larger yet.
And it shows up with less than 4 gigs total because in order to call it a 4 gig, or any other sized, card you just have to be within rounding to it. The higher the class and better the brand of card, the closer to being a true 4 gig it will be. There is also going to be space reserved for the formatting of the card et al. My 8 gig card shows 7.7 gigs total space.
