I just bought my 2 - 770s. Here are my best answers. "1. Is there any way to change themes?" Yes... "2. can you listen to music while browsing the internet?" Yes... "3 How good is the video playback on the Nokia770?" With proper conversion, not bad. "4. How long does the battery last?" 5 to 6 hours "5. Can you watch flash videos online?" You can its just ot so great... actually, just short of bad. "6. I heard that theres a notes application, if so can you write a note then copy that and send it to someone via email?" ... I haven't tried, sorry. "7. Does it come standard with AIM, YAHOO, MSN, and GOOGLE TALK messengers?" It comes with Google Talk. You can use GAIM or other IM applications that are EASILY downloadilbe and configurable. "8. Does the audio player display album art?" Not that I have seen... but some of the other media players might. "9. How good it the audio quality?" The external speaker quality is good considering its size... but the headphones jack works really well. -------------------------------------------------------------------- I hope this helps!!! I am very happy with my purchases!
