Sorry, couldn't think of better way to put the subject.

I am currently using a GeniusLite modem on the ADSL (LLU) service with phone plugged into wall jack.  I am due to switch to fibre in about 3 weeks.  My question is, will they have to send me a new modem or can my current one be remotely firmware upgraded for fibre.  I am not wanting the handset model as I will plug my current phone into the side.

Cheers.
