Hi Everyone
So I finally got my N900 just under a week ago and I have to say I'm less that impressed with its performance. Some of the problems I'm having include:

• Freezing up in Applications manager: I can't do ANYTHING else on the phone while downloading something.. if I try I have to reboot
• Phone Calls: when calls come in the phone often freaks out.. Sometimes displaying a blank screen so I can't tell who's calling and I can't pick up the call.
• Another call issue: sometimes I can't hear the person on the other side of the call and they can't hear me.
• Yet Another call issue: I can't receive calls/ messages while on my network internet (3-3.5 g) but Ithink this might be a common bug.
• General: occasionally choppy for no real reason... I downloaded the system info widget on the desktop and my CPU reads 100% when I have nothing running which is really wierd (I even closed IM, WIFI, weather, facebook, etc and it still did the same thing).

There's a few other minor things but I mentioned the most annoying things above. I got the phone brand new so I don't really think it should be doing this.. Is there something I'm missing or do I just need to flash? If I do, can someone direct me to instructions on how to do so?

Thanks heaps in advance!
