But it is important, it shouldn't be seen as 2 separate devices, just 2 
partitions of the same device.  Unless, of course there's something in 
the firmware that makes the drive into two devices.  So, instead of one 
1GB flash drive it's literally broken into 1 950MB drive and one 50MB 
drive.  (Make sense?)  (The file sizes are for example only).

If the storage is physically divided that way, then I'm not sure merging 
the two together to be a good idea.  You'd need SW RAID and it being a 
mobile device I don't know that would be safe for the data on the device.

I hope at least SOME of that made sense.
