T80 don't seem to respond to any tag

Hi

I am very new to T80 though I have done NFC development on Nokia 6131. I just got it last month and when I first got it, I activate the NFC functionality in the "Settings" and try to scan a iso15693 tag without success. I could scan the same tag with a nokia 6131. Basically the phone did not vibrate or do anything at all.

my VM version is v3.3.4,20080609a

Also the battery is EXTREMELY difficult to remove from its slot. I broke my nails trying to get it out and it's still stuck. I have to use a paper clip to remove it. Very very bad design else I got a defected phone.

pls advise. All help appreciated
