Hello All 
Would you like to update your BT350 (RD530 in my case) to the newest firmware v.3538 and driver version 5.0.1610.0 ?
Here you go: ftp://ftp.us.dell.com/network/R155172.EXE
It's actually for Latitude D630 and internal BT TM 360 , BUT! it works
There are 3 DFU files with the newest firmwares for BT 350 , 355 , 360 + EDR 2.0
After flash you'll get the device i.e. "Cambridge Silicon Radio" DELL EOWYN V3538
