Spark is providing a firmware download for the Huawei HG659. I note there has been quite a lot of discussion regarding the VF version of the modem, and how the VOIP is useless for any other SIP provider, as it's hardcoded into the firmware.
I am wondering if anyone has tried Spark's firmware download. Does it work? Does it fix the VOIP limitation? Are there any down sides?

Anyone braver than me willing to find out?
