Thanks guys for your help. it is the phone tho, cuz when i put her sd card back in her blackberry. It was corrupted too so i formatted hers and it started working fine, so i tried that with my SD card i beleive that it is not compatible with her phoone being that it is 16 Gig aand a class 2, because it recognized it but it would not format or do anything

. Anyway I have a new phone on the way

but the lady said the sd card is an accessory and not coverd under the manufacturers warrenty

. so once i get my new phone it will hopefully recognize it other wise i will do what you said and take it to the store to see if they will exchange it but i have my fingers crossed.
