Query: Unstable, looses power, looses memory

This phone is a great idea but is very poorly executed... you can't login to networks where you need to confirm a key via the web...as it is the case with most hotels.Additionally the most recent firmware makes the phone very unstable, every 10 minutes in a call it just switches itself off and you can be lucky if it doesn't forget you network key...can be really annoying.I will try to return the phone even though I like the concept and the idea. The only way I will keep this phone is if Belkin comes up very soon with a new, more stable firmware.
