Default Orange (UK) Line 2

I just received my new I-Mate K-Jam (soon to be the SPV M600 I believe) and was dissapointed to find that it does not support Orange Line 2. I spoke to Orange who informed me that it is not the only device with this issue as the SPV M5000 (Universal) also does not support Line 2.

I have been using SmartPhone devices until now and I can confirm that line 2 works great with these.

I am not familiar with the any previous phone edition Pocket PC versions , so perhaps you could let me know if this has this always been an issue, and if so, if it is due to be resolved in the near future.

FYI: when a call comes through on line 2, the number (and name if in the contacts database) is displayed on the screen as with any other call, but with an incoming line 2 call no ringing or vibration is apparent. If the caller leaves a message, then the right hand side of the spool fills to tell you that you have a message on line 2 as per usual; however, you are unable to access the message as you cannot change from line 1 to line 2 and cannot therefore make any calls on line 2.

Please help!!
