Cell Phone Connection - Will this work?

I find myself needing to dial into a remote PSTN modem connected to a land line which is connected to a PLC, but I only have a cell phone. I came accross a device from Siemens the Siemens Gigaset One Cell to Home Extension. ( http://www.smithgear.com/itc-bt.html ) I'm wondering if this will work?

I would connect my iphone4 through bluetooth to this device and my laptop modem through a phone line also to this device. Now the modem can get a dial tone and dial out through my cell phone (iphone4) into the remote modem.

Any thoughts why this will or will not work?

I don't think it'll work. Oh no doubt about the BT connection & modem & device, but rather the phone conversion of the analog signal to digital. Perhaps at 300 baud.

In days of old, we put out cell phones in Analog Only mode for modem use. In the modern digital only age, the rules are different.

for some info.

Thanks for the info. I guess the problem is the manipulation of the analog signal to digital by the cell phone. Hopefully somebody comes up with a device that could bypass this problem, otherwise I'll have to keep my land line just for situations like this.

I forgot to add, the also in day of olde it was quite common to connect your laptop to the phone.

You could get an adapter cable that would plug into the phone and the other end was a DB-9 serial connection for your computer. Using that, the phone became the modem itself.

Maybe Apple has some solution. You might want to ask over in http://forums.macrumors.com/forumdisplay.php?f=103 or at http://discussions.apple.com/category.jspa?categoryID=242
