Today i-mate has released a solution for the i-mate PDA2k Bluetooth problem which caused a lost of bonded devices like Bluetooth headsets.
They have been working ceaselessly to fix this issue which had his root deep within the Bluetooth stack and took longer to fix than anticipated.
However,, now the fix is available on the support page for the i-mate PDA2k and is approximately 3.9 Mb in size. So it's a cab file only, not a completely new ROM update which is expected to be released soon.
The Bluetooth fix is available for registered Club i-mate customers only (registration is free anyway for i-mate device owners). As far as I've heard, the T-Mobile MDA III has the same problems but so far T-Mobile haven't released anything similar. The European Xda III/IIs is expected to be released including this fix/updated Bluetooth stack.
