They have left out simple features from Skype for Linux - like hiding people who are not online.

Best OS? If WinMO is the best, why are they releasing version 6.1, and work for 7.0? WinMO is quite useless. And languages? I'm hungarian, and there is no hungarian language in WinMO 6.0 (for Smartphone)

too bad you can't do that, only if you own www.engadgetmobile.com :-)

although it is a purely personal opinion, but this device looks really ugly...

I don't like any advertisment on my mobile, not even the lightest ones...

Can't you buy a carrier independet version? Here in Hungary you can buy almost all phones sim-lock free (though they'll cost a bit more)

This user is simply stupid, and the carrier is irresponsible not building security into its service. It is no use to let users (even accidentally) create such a huge bill, when the carrier exactly knows what amount of money their customers are able and willing to pay (that's called marketing). Here in Hungary if you use a service and use it about 150-200% more than in the previous month, you get an interim bill. If you reach ~300% usage, the service will be disabled, until you pay the bill.
It is like blocking premium-rate telephone numbers by default, and let the user enable it.
