I had the latest version of this PocketMac Phone (3.4.1) installed on my G4 Powerbook and I can only confirm the problems and side effects this "software" generates. The most annoying thing was the the multiple associated daemons chew up to 70% of the CPU cycles. Plus, it looks like this software uses kernel extensions which is apparently not very good practice. I mean, how can any company release such a piece of sh** ??

Now I'm loosing even more time to try and get my money back but the company hasn't answered to any of my email request as yet and it doesn't look like they ever will.

Never have I had such a bad experience on my Mac. Just goes to show that one should always read the reviews before buying !
