I have read 4gb will work in the Scurve can you go bigger? Has anybody tested this?

4gb works with 4.2 on the curve. 8gb is not supported with blackberry OS 4.2. It is supported with 4.5 and works (I am currently running the 4.5 beta) and have an 8gb card working no problem.

Also since you are using an 8330 (blackberry OS 4.3) 8gb is supported with your os.

I just got a 4gb for my curve on 4.2 and it works fine

I got a 4 Gb and am now wishing I'd spent the extra money for the 8 Gb. Depending on what you're planning to put on there, 4 Gb is not that much nowadays.

my 8gig micro sd works just fine on my 8310

as does mine. I was afraid it wouldn't work well, but it works just fine

For those with the 8310 and the 8gb card, what OS are you currently running?

I have a sprint 8330 curve OS 4.3 with a 8gb HC card, works great!
