15GB of 'other' data on iPhone even after iTunes factory restore...

Hi,

Does anybody have a solid idea how to reduce the 'other' data on the iphone?

I have just under 15gb of 'other' data on my phone which I think could explain the slow operation when using it.

I've done a factory restore and it reduced the 'other' by 0.3gb. Not really worth the waiting around.

Any advice is most welcomed.

Thanks,

Chris
