I just got this phone

After using it for a day, I've some questions

1. It was sold in Singapore but I'm stayin' in Malaysia, should I register with samsung.com.my?

2. Is the ZAGG InvisibleShield compatible with the OLED screen? Application uses water, will water damage the screen?

3. What's a good place to download widgets apart from the phone's default widget downloader?

4. Where to get other Symbian apps/third party games (I was a SE user before)

4b. Can I get another browser alongside the default net browser?

5. During calling, I found the volume was quite low unless I activate the speaker (holding hold key, select speaker)... is this normal?

6. What's a good free software that adds album coverart to songs?

7. How to make the GPS map function work for malaysia?

Thank you!
