Hello guys, the telephony part of my N900 is falling apart. It drops calls, randomly drop the network and doesn't reconnect and almost continuously display one bar unless I'm standing extremely close to a tower... I'll keep the n900 as a small terminal for my FreeNAS since wifi still works, but i need a replacement phone, I have to choose between the N8 and the HTC Surround for $350. I am on AT&T, which one should I buy?
