I own 640 and my friend own 730. 730s camera is more superior than 640. In other departments, 640 is better. The display in 640 looks sharper than 730.
I keep wifi Bluetooth 2g GPS on always. Configured 4 email accounts to sync at ever 30 minutes. I use WhatsApp. From 100% in morning at 6am, by evening at 10pm, I used to have 50-60% battery left.l

I have updated my phone to Amber. Everything is fine. The error mentioned may be due to data network problem or server problem.

This problem is not linked with Bsnl. I am using Idea. I am also facing same problem. Restarting the phone and laptop works for me.

I have same problem with my Ford and L720. The problem exists with Android also. Only thing we need is a option which medium the maps should use. Bluetooth or Phone Speaker for playing the voice.

Android is in almost developed state. The future updates will take longer to add new features. But in case of WP, there is lot room to improve. So everyone with a WP will expect quicker updates. Earlier Android got updates every six months.
